Just started a job at a cnc milling shop with alot of benefits but its been about a year since I got my degree so theres some things Im having some difficulties with shop culture and need some general tips. supervisors know im pretty green but i dont want to seem like I dont know jack shit so every night has been me studying up as much as i could to rerember things. any tips you guys could give?
>>2959789>any tips you guys could give?czech the catalog before posting because we already have a button pusher thread
>>2959789Better to acknowledge that you don't know shit than trying to pretend that you, at least starting out. At certain point you can start pretending, but that will come much laterWhat sort of tasks does your job actually entail? Any programming or devising set up schemes? Are you getting any specific training, or just getting thrown on the floor? Mass production, job shop, or something in between?I have benefited greatly from just knowing how to use a $15 scientific calculator and keeping a cheat sheet with trigonometric and other geometric formulas. I suck at math, but people think I'm a genius because I can figure out 9th grade level math problems. Don't rush yourself trying to prove a point. Keep notes both for general long term use, and for specific tasks (offsets, feed/speed overrides, etc.) If you do your own deburring, make sure your files are sharp and regularly cleaned and build an arsenal of scrapers, stones, and sandpaper. Get a good magnifying glass or loupe and learn what the different wear modes on cutters look like; don't be too hasty to rotate inserts, but don't wait too long either.As far as shop culture that really depends entirely on your specific workplace. On my shift most people get along well enough and help each other out when asked, but there isn't necessarily a lot socializing. I'm only the third most autistic guy there. The prior shift though is dominated by bullshit politicking and posturing.
>>2959802They're having me check the parts, meausre it out and set up the machine. once part is out measure it out and repeat till job is done. its i guess a button pusher job with extra steps. i do have to do my own deburring at times. the programming is from a seperate group of guys in another room but we have to put the program into the mill then set up the X Y Z to make sure things are correct. once the first part is done send it up to some guys who carify its good then just run the machine till i meat the quota for the job. usually go and measure after every part gets milled. sometimes when we have to make adjustments because out tool is very slightly different then we go in and change some settings around. They are basically throwing me on the floor with my trainer and theres not really a paper stating "learn this" which is annoying but understandable. its not that I hate it its just kinda a shock to get into.
>>2959789Don’t learn to setup or program You will be expected to do so without any increase in payThere is a trend in jobs right now where you get an entry level job at entry level pay with senior management duties
Learn to call out tools, the probe should be no1 then find z axis point 0 on the top of the viceType as followsG54 G0 H1 Z-30M3 s12000 M8 M7Z200X100X0Y-200 Z-40 M114M5M4 S12000Z25 (SAFETY DISTANCE)Then press start, its the green buttonIt will set the machine tightAlso, make sure to read the technical drawings well, and when you have a stock ready, get some oil any kind and gently rub where it will be cut, massage it for 15 to 20 minutes especially if it will be drilled and cut with a roughing millThe rest you will learn as you go, depending on how far in the buisness you want to reach, also >>2959806
>>2959802//threadAlso be autistic, follow your leads instructions exactly, take notes, if any issues come up, tell them first and consult with them before you change a process. If a process changes, do a part check if possible to make sure it still works. Get a Machinery's Handbook and study from it. I keep a binder filled with notes and infographics of esoteric knowlege. Check your vise/fixtures at the start of the shift to make sure it's trammed and parallel to the table, because you have no idea of what night shift gets up to. If you get lackadaisical or lose focus, step away for a minute or two to re-orient yourself.Advice from a fixture builder I worked under:>"Clean, Square, 90°, parallel, flat, perpendicular" EVERYTHING>"Don't trust anyone" (Especially yourself)>"You can never have enough hammers">"Drink from the skulls of your enemies."
>>2960004I get the joke, but that code would just instantly throw an alarm.
>>2960004Don't do this. It creates muriatic acid which will kill you.
>>2960795Can you close your eyes and see where and how the machine goes if you read the code prior?Download one of the free gcode programs, all they mostly serve for is editing simple things, but also show visually vectors which represent the tool tip movements.They are also used to send the program to the machine or machines have usb ports, but it doesnt hurt to first make the program on the computer first, have it show vectors and coordinates of the vectors, then send it to the machine, if the program involves multiple tool changes and offsets where you have to repeat the segments until you get the tolerance needed.Start with drilling first, do drills and rounding up stock, you will advance further once you get better and faster.Speeds and feeds go on instinct, calculations dont work too good on dull endmills and tougher materials, you start copying others at first, then you create your own system and rules.And write down everything at first
