How do you set up compact machine tools like shapers on uneven ground?
I know you're 'supposed' to pour a slab.
But let's say you dont and you'll use adjusting machine feet to compensate the ground.
I know how to level a lathe and analogous to that you'd probably want to pull the ram out and measure the entire alignment to set up a shaper.
There must be an easier way.
Lets say the machine has either 4 or 6 feet. Wrenching feet until they all end up at the same torque seems wrong to me as this means equal load per foot but ignores actual weight distribution. one could determine the center of gravity first and calculate how great of a share each foot needs to carry but again it's unpractical.
In case of the machine with 4 feet I sort of have the idea of balancing it on 2 diagonal feet and then cranking the opposite ones out until they are at equal load (this assumes the center of gravity is symmetrical in one direction) but the 6 foot machine would again not work like this.
I sort of suspect one wants to just measure the underside of the machine between feet to make sure it's straight.

a shapers about at the far end of the spectrum of wet noodle machine tools. theyre from an era of dirt floors or at best lumpy wood endgrain blocks. plus the nature of the cutting force requires the frame to be inflexible. and a shaper aint exactly a tenths machine gnawing away at some rough blob of cast iron with a hand forged gooseneck tool

My situation is like you describe: Got two shapers here, had a plander which is rather set up like a lathe, different story. I just put them anywhere and make chips, move them around once in a while.
But lately I wanted to tidy up and I always had the line from one of the shapers manuals in the back of my mind where it says to pour a slab and make sure it's flat within x, or the manufacturer wont guarantee dimensional accuracy.
Sure it may be a purely academic discussion but still: There has to be an established method and I believe you can run the gib just ever so slightly tighter if it's really dead straight.
On a sidenote: Recently I lifted the shaper on 6 feet somewhere else. I've put it on some blocks. I was surprised to find the blocks in the middle to be loose, i could just slide them through underneath. I left them under the feet, came back lately and found them to be completely stuck.
I think the machine has deformed by at least a mm and back again over the course of lifting it and setting it back down. This sure doesn't translate 1:1 to deformation at the top but I expect it to have some effect up there.
Otherwise it has something to do with the elastomer in the feet doing funny things.
>picrel shows the feet someone else put on
This one is my later addition to my shapers and slightly bigger than the one on 4 feet (flat base really, 4 holes for bolts). The planer was an entirely different beast but wasted way too much space.
It's just 'tism, OCD and curiosity if yiu want.

>>3002068
it would be pretty easy to experiment with flex by putting a mag base at the far outboard end of the table with the indicator zeroed on the vertical ways up near the top. then pry up on the machine base in a few spots and see how much it deviates
the rubber feet seem to me like the wrong choice as they negate the foundation connection. idk just gut feel
a hand poured 3 or 4" monolith pad under the machine footprint would be an improvement if you shop is otherwise lacking then level for setup convenience with hardwood shims
thats a gorgeous shaper in picel

>>3002078
Thanks.
>elastomer feet
I see the same issue. I wouldn't feel safe with full steam on any shaper that isn't bolted down and while it seems to make levelling less of an obvious exercise om the other hand I can see how the rubber might simply negate some roughness.
Shop floor is really nice btw. Like I said, it's an academic exercise mostly.
Not sure about your idea tho, prying in random places with a constant load results in deflection in other parts, depending on the geometry and the distance from center of gravity. But it wont tell you wether the machine is flat and every foot loaded according to the weight above it.
I'm thinking for the rams bed at least one might be able to use the ram, in place, as a straight edge. And some feeler gauge, see if the gaps change with the load on the feet.
Perpendicularity of the table shouldn't be too hard either. Perhaps cut test pieces and test that instead of being square it cuts square.

Please go back to africa. You've been shitting up thread with your retarded nonesense and getting nothing done for ages.

>>3002034
You're overcomplicating this. There's a million reasons a machine frame can become bent or twisted over its lifetime so it's perfectly normal for its weight to not be distributed equally over the feet. Just do what everyone else does and align it with a precision level. Of course, any rubber feet can and will throw that off both over time and under work load, ideally you want to bolt it tightly to the slab, effectively integrating it into the machine structure.

>>3002597
I know that I am overcomplicating this and like I said, I have ran both shapers and a whole host of other machine tools without paying particular attention to this. Only on 'long bed' types of machines I used the well documented approach amd made sure it's straight.
I would still want to know how, in theory, one sets up a very stiff machine with any number of feet just like it was clamped on the milling machine in la factoria.

>>3002609
>a very stiff machine with any number of feet
Then it doesn't matter and it's more about stopping the machine from crashing through the floor or sinking into the ground by spreading the weight over multiple points. If your floor isn't particularly weak just crank it by feel until it feels about the same

>>3002620
>doesn't matter
As explained above: Negilible perhaps but the effect will be there. And since machines come ona spectrum from noodly toys to stout as frig there will be plenty of edge cases where the machine is not stiff enough to just sit on a pile of bricks but at the same not have a geometry suitable for easily checking alignment. Checking alignment would be dealing with symptom anyways, the root cause is the wonky foundation. As such there ought to be a commonly agreed on procedure that allows you to achieve good alignment with reasonable effort.
As I have explained above the machine, last time when I moved it, must have deformed first from lifting and then again deformed in the opposite manner when sitting on some blocks. Movement at the base of such magnitude certainly translates to some movement in critical places.
>inb4
just put her on 3 blocks and loosen the gib until she runs free
That's how you transform your situation into a thirs world situation.

>>3002620
forgot:
>about the same
but this is arguably stupid and retarded as there is no rational basis for the idea
a machine tool is not a homogenous cube. A lathe for example will be heaviest at the headstock and maybe heavy at the taikstock, lighter in between. Simply not taking measurements along the bed and cranking every foot so it 'feels the same' translatea the torque by means of the screw such that the load on every foot is equal. This will cause feet under the bed to share load from the far ends and uktimately raise the bed in the middle. Hence every normal functioning human ssts their lathe up using a level, test bar and or or other methods like taut wire etc.
Just that checking alignment is a bit overkill in case of a shaper especially if it includes pulling the ram, which in case of one of my shapers requires you to start draining the oil.

>>3002647
It's either rigid enough and you do whatever, or it's not and you use a precision level. If in doubt use the level. It will show deflection long before anything starts to actually jam.

Cast iron frame shouldn't bend any noticeable amount over time just from sitting on the floor unless it's cracked. Rubber feet can and will sag but you shouldn't be using them (or wooden blocks for that matter) anyways on a machine where feet alignment affects geometry (and if the manual says to pour a slab then it most likely does). They're just too spongy compared to both the machine and the slab underneath to provide any adequate support in this case.

Particularly for a shaper like this >>3002068 you don't need anything, it's beefy enough to keep ram and table geometry when not in use without any special feet alignment. But it relies on its front pair of feet to help resist cutting forces after you lock the table down so you want to make sure there's no slop in them, rubber feet included. The forces will also try to lift the middle feet upwards under heavy load so it might be not enough to just have them tight against the floor, you'll need to actually bolt them down using anchors.

>>3002705
>shouldn't be using them
In case I didnt make it clear:
I was 'refurbishing' a little so I stashed several machines away, only for that purpose did I set them on wooden blocks. But you might be righg that it actually was the blocks that gave more than the base.
>jam
There's a wide range between aligned and jamming. Seen enough machines in my life where some doofus just relaxed the gibs whenever something was wrong.
>Rubber feet are spongy
True they allow motion. But it set up right the geo. etry will at least be close to what it should be at all times and what it should be on average.
>Bolt down
I always bolt down both shapers of course and their bolts are still there. Those things will really walk through the shop.
>For a shaper like this its irrelevant
That is not the point and it's quitw surprising I didn't get that across yet. Ignore the shaper if that helps. Imagine I had an undescript machine toolbor any other structure and it needed setting up on feet such that a previous alignment is recreated and it will sit free of ingernal stresses. Imagine it had N feet and accessibility to functional surfaces was poor - unlike the bed of a planer or lathe. This is not a new problem by any means and I bet there is a well documented method to achieve it that doesn't involve disassembly, autocollimators, test bars o algo. Probably some method by which to at least arrive at a close first guess.

Naw the moment you move some part of the machine to a different position, or put a heavy part onto the table, or there's some dynamic force, the loads on the feet change and all the alignment goes out of the window. Rubber feet are orders of magnitude softer than the machine itself and will easily give to any twist (remember we're talking dozens of microns of movement or less), so they effectively provide no support as far as geometry is concerned. They can also sag over time under load and swell from oil (even from touching oily chips on the floor), and it all depends on temperature and even humidity, so it will absolutely make trying to align a machine that's sensitive to it a living hell.

>This is not a new problem by any means
There's no such problem because small machines are rigid enough to not care, and you don't move large machines often enough for proper alignment to become a hassle. If you still really really need to, you can add or machine some reference points near the actual bearing surfaces to use for alignment.
Aligning by feet loading doesn't seem very reliable because you can ding or bend the machine slightly during the move, or fail to put it in exact same tool position and configuration (which is also important) and it will throw off your setup so you'll end up having to check the primary surfaces for alignment anyways. There's also the issue of both measuring the loads and recreating them accurately and without throwing the original alignment off in the process.

Do you even really need to measure the internal threads? If you're making something from scratch you can just make the external threaded part first and use that as a plug gage, and I'd much rather have a set of telescoping gages than that janky caliper.

That caliper won't work for thread measurements btw since the tips are lined up so it'll either go in crooked or one side will be in a groove while the other is on a peak if you can somehow hold it perfectly aligned, which you probably can't.

Also if you have a decent way of measuring an external thread you can just make your own plug gages.

Also also chances are it'll be cheaper and easier just to get a tap and use that instead of fucking around with internal single point if you're not in a production environment.

They skip more than that. Last I checked they had 20 prefixes. Scratch that, I looked again and they added 4 more in 2022. So, 24 prefixes now. How many did they have in the beginning? 6. How many of those did everyday people use? 4. Now that we have 24, how many do everyday people use? 4. The same 4 from 1795? Yes.

Insanity.

>But they are in powers of 10 so they are easy to remember!
Yeah, except all the ones they added after the original 6 aren't. Once you hit mega/micro it changes to powers of a thousand. You'd be surprised how many people that grew up with the metric system don't know that a megameter is not 10,000 meters (kilometer times 10, 10^4) but 1,000,000 meters (10^6). Or that a gigameter is a billion meters (10^9). Of course, they never use those prefixes so why would they? Overall, I like the original system. Hell, I even think 'ares' are cute. What I hate is all the changes. Even when the changes made sense, its like, why didn't you do that originally if it was so important? It is not like we're new to the whole 'making measurements' thing. How did you miss that? Meanwhile we still use hectares even though they were dropped in 1960 and we will probably be using them until the end of fucking time. Like how the cubit is still in use in some places. Assholes.

One thing I absolutely will not cotton to is Celsius/Centigrade. The freezing point of water is zero? Really? That is not even that cold. And 100 is fucking boiling? Fuck. Fahrenheit had it right. 180 degrees between the two. For everyday people Fahrenheit is perfect. That way zero is fucking cold, 100 is fucking hot, and who gives a shit about anything else. Oh, you don't like that boiling is 212°? What the fuck do you care? When was the last time you had to get something to 212/100? Is is the boiling you want, not the fucking number.

For science? Rankine or Kelvin. Zero is zero and negative numbers can fuck off so there is no confusion. Fuck Celsius.

The metric system is great and you're just too dumb to change habits.

Nobody uses decimeters and serious people don't use centimeters either, you make jumps every three powers of ten.

You'll use microns, millimeters, meters, kilometers. There's nothing you can't do with those.

Using freezing water as the zero for temperature means you know when it's freezing outside without remembering a random number.

Hi all.
I've recently finished building a furnace capable of melting roughly 55lb's of cast iron at a time, for use in casting and building a CNC machine for primarily machining metal parts. I'm planning on a belt driven spindle using a 1kw servo motor, Nema23 stepper motors (non-closed loop), haven't decided on the size of the ballscrews or linear rails yet.
Would it be better to design a mill style machine, or a gantry style one?
I am a little worried that the nema23 motors won't have enough torque to move a cast iron gantry around.
Are there any small quality of life features I should plan on trying to implement before I start designing in Fusion?

>>3006482
Well, I don't think you've thought of the sheet metal in the rails and the poor allen screws tasked with retaining a cast iron weight you plan to throw around at high speed and direction changes.
Or like, what is it you're casting, the housing for the spindle, chock and axle? You can't wrap a couple bearing sets in something premade or sheet metal?
There is the other hardware to consider as well. I'd put rubber bushings between a lot too.

Oh you're the slot car guy. I was wondering what kind of use oval punches would really be. I've rarely needed an oval hole, and really it was more of a slotted hole for sliding adjustment rather than an oval. Also what kind of thickness can you punch with 6 tons? Obviously lighter gauge stuff will be fine.

>>3006538
It's all light in my world. Every press I buy, someone will inevitably recommend the next weight level for "real uses". But it's great for everything I want.
I'm doing more than that but slot cars is my focus. I'm doing idiot suburb yard art. Home repair. Modding the smoker/grill a lot. Just shit.
I can punch slots and use slot, tab, notch based constructions too.
And of course think of the transmission plates in manual cars. Just slot dies really.
I don't need to make money or any thousand pieces. I'm just enjoying myself.

>>3006538
I'd also like to make contraptions that at least work badly once to drive my neighbor insane. He's a by the book 1970s throwback and if you're not using authentic not chinese OEM he's horrified. It ruins his day when I invent things.
"Well ya... ya got some tension problems, do you have a manual? Did you use ANY oil or anything? Have you got any lock-tite? Boy, you should just buy ____________."

Oh hey, that german pitch tar stuff used for stamping, can I recess a small shape in plate mild steel? Like circle or oval, by stuffing a die for a floor plate?
Or is that forbidden unorthodox thinking?

>>3006590

I don't know what you're talking about with german pitch tar, but do you mean like using a rubber sheet to form material over the die and push the material down into the oval? I'd imagine the dies would be too sharp on the edges and still try to shear the material, but if you're just fucking around you could try it anyways. Maybe use the bottom side of the die and chamfer it with a nice smooth radius and try that too.

>>3006604
No stuffing the die part way with a really stubborn hard pine tar to make a floor that stops the material and creates recess shapes. It's used in stamping copper. And it doesn't have to do a wonderful job, just kinda.

I can drill holes and like face stuff with it on a good day


I use cnc machines in MDI for most of the manual stuff I need to though, plus enclosure and flood coolant and I don’t have to worry about out if climb milling will destroy my mill or not

>>3006704
I have the same one, how much did you pay for yours? I paid exactly 100 dollars shipped

>>3006825
$79 at the Depot.
It's nice, I see it's limits but I'd hardly exceed them. 1/4" flats and bars is about it, .032" cover plate steel is most of it. And softer decorative shit, brass, etc.
It took about $400 to get ovals, squares and padlock tab shape (1" by 1/2", rounded on one end and bent 90 degrees, needs drill hole). Standard 110v outlet die was most expensive.
They're spring return thankfully, not pound outs.

I didnt realize how expensive shipping can be. I saw a small shop for sale for 8000 with a bridgeport, a lathe, a band saw, a grinder and a welder.
But it would have been like $7000 to get it all shipped to my state. I see why some of these really big machines sell for so cheap used. It costs 4x as much to move it as the hammer price.

so learn how to do your own rigging
most deals are cases of having about 3 hrs to make shit happen so you best have a trailer ready to go
in this day and age a rental drop deck and a pallet jack make it pretty easy for things under 5k lbs

>>3006892
In some cases it's cheaper to rent a vehicle from there to your destination for the equipment, and just fly there or something. You can basically devalue your tim and swap out the labor and driving end of the cost if that's a significant part.
Also look for an indy car seller. Wheels is wheels, they'll ship due buggies and all kinds of shit and all they want is roll on-roll off and the ability to drag it on with a winch. If you can pay someone to drop it on a rolling pallet or some shit you can probably negotioate a cheaper pickup on a half loaded car trailer.
Wait till it's "home" and then has to move 6 feet left lol.

how do i get my dad to stop destroying my parting tool holders and inserts?
he's destroyed 6 of them (not the inserts, the actual insert holders)

why is cast iron so fucking expensive?

>>3005684
i hate this shit so much
i need to cut metric threads
only way of cutting metric on my lathe is to leave the half nut engaged the entire time
i have to shut the machine off before the tool crashes into the chuck, switch gears to reverse and back out

is this common on all lathes or just dumb hobby bench tops?

>>3002068
is there a nicer sound in all of industrial processes than what a shaper makes?
i can't think of any
literally the most pleasing sound ever

>>3005230

I have igaging ones
they are fine
honestly probably overpaying with them
calipers are not precision measuring instruments despite what people parrot
cheap ones are just as good as mitus

>>3005252
yea the battery life on the iGaging shit is some black magic fuckery
i have no fucking clue how they last so long...my 4" calipers are 6 years old, I always forget to turn it off and have never changed the battery in it, it doesn't have auto-off either like the newer ones

>>3006937
Never heard of that brand everyone I’ve worked with uses mitutoyo

That auto off remember where it is feature is really nice

>>3006933
>s this common on all lathes
yes because of how an english thread is a inverse of an inch whereas metric are a multiple of a mm. the thread dial on reads off units of full and half inches relating to the travel of the pitch of the leadscrew. say the leadscrew is 4tpi so every 4 turns equals 1.0 inch of lead. so when its turning without the halfnuts in youre watching for the point to come along tver coincides with a multiple of 1 inch that evenly divides into the pitch of thread youre cutting. hence why even pitchs are any mark because in a 1/2 inch theyre still a whole number
metric on an english screw is a can of worms because the mm pitch doesnt evenly divide into whole inches that are read off on thread dial. in theory there is a number of turns where the multiple of the mm pitch will sync up with a whole inch but it would take usually high hundreds to thousands of turns of the leadscrew to reach the point and theres no way to count plus the time would be hours
even metric leadscrews suffer because for example 0.7 pitch to cut doesnt evenly divide into a 5mm lead screw so if you open the halfnuts the sync is lost

>>3006962
theres a trick to cutting mm threads with a thread dial on any lathe
you engage on 1 or whatever at the start and that will be your number for the entire job. so you cut up to the end of your thread and open the nuts and pull the tool back if you dont have a relief. then immediately turn off the spindle. now slowly reverse the spindle until 1 (or your number) on the dial backs up to the mark then reengage the halfnuts and use spindle reverse to move the carriage back to the start of the thread and take your next cut as usual repeating the process

>>3006714
>because he can't understand Fanuc macros.
On this note, I'm kinda stoked because I start CNC/programming classes in a few weeks, and my school has been all-Haas for years but they JUST got and installed a lathe (DN I think?) with Fanuc and a Mori VMC with Mori's own controls.

I guess I'm the opposite of Sieg there, I've just spent a year on Bridgeports and manual lathes (plus some supporting stuff that feeds into CNC like CAD classes, QA/reverse engineering, etc.) and only now about to start a year of CNC.

>>3006967
fanuc is great for documentation and user side repair but holy shit did the nips make the control interface fucking bullheaded retarded like needing multiple screen changes to set simple fucking offsets
idk why cnc controls have to be this gayass walled garden thats hard to use and thats not to mention super retarded shit like backwards offset direction on daewoo lathes
mach3 is fucking trash but its so goddamn nice to just use the mouse to click on the axis position box and type "/2" and instantly halve the value or whatever you want. and then run cad/cam on the same screen and do 1 off shit in minutes without transferring a file or having to fuck with wear offsets

>>3006963
So basically you make sure the thread dial doesn't make more than one revolution and back it up to get back on the same thread again? Makes sense.

>>3006971
For me it's mostly just that Fanuc seems to be by far the most common in the industry so having some familiarity with it is a big leg up vs. only knowing Haas.

Japan has always been fucking awful about software UI/UX in general. I've experienced it across all kinds of industries - car infotainment, camera menus, printer software, and so on, it's all super clunky and always looks and feels like something from 15 years before it actually came out, which is especially bad now because the early 2010s were a terrible time for software.

>>3006963
I tried this from the Oxtools vid on it but I can't change gears on my lathe when it's running, when I put it in reverse I still have to wiggle the lead screw or spindle to get the reverse gear to mesh and this screws up the position of the halfnut on the leadscrew.

>>3007110
reverse the spindle not the geartrain tumbler
if you move the gear reverse during threading you lose sync between the spindle and leadscrew
theres lathes with a dog clutch leadscrew reverse but you dont have one

>>3006967
> Moris own controls

Nah senpai Japanese Machines are either Mitsubishi like mazak or fanuc

The German and albeit shitter side of the Mori partnership with that weird wireless service key and shit is Siemens


Easiest tell is open the cabinet, bright yellow deco drives are fanuc white is mitsu

Mori calls shit msg msx or whatever else as a gimmick

>>3007002
Probably but i don’t think manufacturing is really an industry where you need to worry about such things. It’s literally a dying industry stateside.

A fanuc backed machine isn’t any less proprietary than haas controls/ Linux/ Unix backed

When you buy a machine from doosan sure it’s fanuc backed but there are a ton of dn solutions side lockouts, additional fees, / service tech only and proprietary features even I/o stuff despite it talking to a fanuc system overall no real benefit imo

I’m also unsure if even bothering to learn conversational via mapps, mazatrol and whatever okuma calls their shit to be a good investment in time.

You’d be better off learning how to fix the McDonald’s ice cream machine as a crew lead and make more than most programmers I knew in a past life

>>3007146
>>3007157
I haven't even seen the machine yet so I'm only going off of what the professor who teaches the CNC classes said when I ran into him a few weeks ago. From what I know it's a pretty new and expensive 5-axis machine that another college bought and then decided they couldn't afford to run. I see that the controllers can look nearly identical externally whether they're Fanuc, Mitsu, or Siemens, and they don't look like panels you see on other brands, so maybe he just didn't realize they were other brands underneath, he's an ex-mil guy so probably never worked with the newer stuff. I'd guess Fanuc since the other machine that came from the same school is running.

Manufacturing is thriving in my area, but I know it's one of the few. Entry level here pays better than a guy with 5 years of experience makes in LA, despite rent being 1/3/-1/2 the price. I can go to Boeing or one of the other union shops in the region and make $65+ within 6 years there, and from what I've been told by people who work there I probably have a solid shot of getting in since I can pass background and drug tests, which already puts me above 95% of people in manufacturing.

Also those Doosan-made machines are ruined for me ever since I realized it was Deez Nuts Solutions.

>>3007160
If it’s 5-axis it’s likely a DMU, probably Siemens

Good luck lol, those things are worse for right to repair than a John Deere tractor, 2000 hour service lockouts etc

>>3007114
ok, will try

>>3007162
I could be wrong about 5-axis too, but yeah, from what I heard the other school bought it and then chickened out when they found out what it'd cost to fix when a student inevitably crashed it. My school does things differently and makes people take manual classes before they can touch a CNC, and then will make people start on the Hass machines before they touch the Mori, so they're more confident in not having to fix it all the time I guess, and the time-based maintenance won't be as big of a deal in a school where the thing only runs like 8 hours a week.

>>3007222
Moris and Mikron and anything heidenhein or Siemens is like a walled garden

Very hard to crash in relation to like a haas 3 axis, meant for production for fortune 500s with service contracts with Mori…

I’d question the decision making skills of a school admin buying one, not much to teach you there

It sounds like you’re in an engineering program

You’ll probably learn more from a clapped out fiberglass spaceship enclosure haas fucking limping along with a chattering transformer held onto the fuck g casting with bent rusty unistrut than on a Mori

Spindle overheat alarm, Mike retap that transformer again bro

>>3007162
do people that run 5 axis get paid more?
would one of those new 5000 dollar desktop 5 axis machines teach how to run them efficiently?

>>3007250

> Run
Depends what you mean by this

Yes, and mill turns and lathes with multiple turrets and multiple axis like b y etc live tooling

Yes, but keep in mind 5-axis parts are stupid expensive, $550 for a renishaw it’s tool setter used off eBay about. I could probably get one for like $300-350 through my junker pals if I needed

Blum laser tool setter? You’re talking about a brand new price of at least $23,000

So higher risk higher reward


> Chinese desktop 5-axis mills

I don’t know… never had one. I’m not sure if anyone with 5-10 years of experience saying “I got one of those desktop toy milling machines at home” will help you get a decent job.

It might help you get a basic operating job though to get your foot in the door after trade school because it shows you have enough interest to put money on the line and won’t job hop though?

Idk I’ve only hired 1 person and that guy quit so don’t take it like I’m some master hiring manager you’re better off asking a recruiter that question

>>3007250
>>3007252
I'm the trade school anon, desktop 5 axis guy wasn't me. Personally I think you'd be much better off with manual machines if anything, from what I've heard a constant complaint from employers is that CNC operators and programmers don't understand the actual principles behind what they're doing well enough because they don't have that foundation.

Really though, for that kind of money, just go take some classes, most local/community colleges will have some kind of machining classes even if it's not as extensive as my school's program. You could also look into makerspaces but it's a crapshoot whether they'll have anything worth using, my local one has machines that have respectable bones (a Bridgeport brand Bridgeport and some quality vintage American lathe, but when I looked at them they were filthy, had antiquated toolholding, no DROs, etc.)

>>3007344
When I worked as an operator we would only use manual machines for reworks, stock prep (if we got a particularly shitty bar cut batch) or just fixture repair

I cut lenses for movies that you probably watched in theaters on an old Korean whacheon though

The problem is most machine shops run lean now, 1 man 7 machines. You can’t really make your numbers for the day if it’s 7 manual machines

Set one machine up, cut a 1A , send to qc set the other cut the 1A while that’s in process and keep going down the line


people romanticize production - some guy that’s taking time painting layout fluid

that’s not really how production works in America

First of all, if you don’t hit your numbers you can be put on a PIP, written up or just let go

I had 30 seconds between yellow light to green light per machine including measurement time

Production is stressful, it’s not slow you need to fucking move

The reason why I have so many snap-on ratchets and impact drivers is that I’d stage each machine with all the tools I needed,
Tq wrench, ratchet, impact drivers, hex bit socket in 4mm and 5mm

I see an m30, slam door open, impact driver on the Kurt vise , vrooom… part out out, wipe it down, measure it. Log it on inprocess inspection sheet,

New piece of aluminum, impact driver closed until click click , grab tq wrench click, slam on harbor freight deadblow to seat that material to parallels cycle start run to the next machine or setup

You really don’t have time to even sit there adjust the knee on a knee mill these days

I used a ridgid impact driver on the knee and even then it was slow

I know you’re in a school environment right now but it’s cycle time is king as an operator and you do that until you can knock out a simple 3-axis setup in under 5 mins

And the operator is at fault if quota isn’t being met

if you meet that quota it gets raised next month so you’re always behind

I’d make 110 minimum small parts daily

>>3007380
Like, there was a common scenario where I’d have 3 side lock cat40 holders in one hand, bondhus Allen keys in my pocket and end mills in another

I’d sprint over to the fixture, quickly set those tool holders up, touch those tools off to my 1-2-3 block I made , adjust the offset (remove the 1” from my block to sett the tools on an invisible plane) then move part stops quickly probe or edge find them

I also had this pretty slick move where I’d rubber band my parallels together and I’d sharpie 1.375” or whatever size they were

And I’d index and pinky one set against the vise with my right hand and my left hand I’d evacuate the old set and keep them in a box near the machine… I could swap work offsets in less than a minute

i did a toauto on a chikom bp knockoff for a farmer for $180 off epay which was the cheapest place i found it. works better than expected and easily repeats within a half thou with an edgefinder
i put sino ka200 micro scales on another machine that i ordered straight from aliexpress in the pre tariff days. it was impossible to get the chinks on the other end of the line to get me a non standard configured scale so i made it work with the cable coming out of the wrong end of the reader for my use. theyre knockoffs of knockoffs and all have the same serial number but 2 micron scales were $65 ea and confirm against an interapid tenths indicator so id do them again
if i was doing another bp id buy the nicer lcd readout box off ali and maybe a toauto 3 axis kit for the scales and resell the box for $50 because that would be the easiest and cheapest way to get the right sized scales
its a joke to see guys putting micron scales on bps because the nicest real bp in the world will can be flexed a full thou just by pulling on the vise handle

I don't do machining but I've always wondered - when applying knurling what keeps the pattern consistent when doing multiple passes? I would think odds are it doesn't perfectly line up so you would end up with the pattern overlapping and offset and it would just look like a mangled mess, but whenever I see videos it always just magically lines up. Does the machinist actually measure this out or is the tool designed so the die slips into place on multiple passes even if it's not perfectly lined up?

careful youre touching on 1 of the longest standing circlejerk debates to exist in the sphere of boomoid machinists
both sides are fully committed to dying on their hill of measure vs mash it in

>>3008135
>>3008137
Whether you measure or not, the first few passes never line up perfect, but once the grooves are pressed in deep enough the knurl will slip to bottom of the groove even if the spacing isn't perfect. If you go slow with a ton of pressure, you can actually hear the tool slip occasionally, but as it runs it'll even out.

You have to provide all your own tools, cutting tools and you also learn how to fix a machine.

My first day I learned what a cnc mill was, I learned what a setup for it was, I learned how to tram a vice, enter the offsets, learned how to use an edge finder and when the machine broke down I learned what an alarm was … what a vector drive was, how to use a multi meter on one to see if it was failing and how to swap one from a sister machine
