how do i find the length of the straight lines

>>16832745First, you need to understand what the chamfer specification means.For example, does "0.5" mean start cutting the chamfer 0.5" from the edge? Or does it mean the chamfer, itself, once cut should measure 0.5" from edge-to-edge?Get back to us with that, OP
>>16832782Why even bother to post that when you don't know anything about drafting standards?
>>16832839Name the ten most popular ISOs?Thought so.
>>16832745Just subtract 1 from 25 and 19, since the chamfers are 0.5 each? Right?
>>16832745I'm not even sure what you're asking.The part described is a 25cm(?) bar with a wider section which is 19cm in the middle. So the narrow sections at the ends are 3cm long each (25-19 then divide by 2). That's self explanitory. If you're asking how far into the piece you should lathe into it then you're shit out of luck because the width dimension isn't given. As long as it's wide enough to fit the chamfers then your part is technically to spec with the information provided.
>>16832745Usually they're 5
>>16832745A chamfer is measured by its diagonal length. So, since you know the value of the hypotenuse and the angle is 45, you can deduce the other two sides of the triangle with Pythagrian theorem.
>>16832745You don't need to. You start with the full billet top the full dimensions and add the chamfers in afterwards
>>16832745Straight lines are all infinite in length, by definition.Do you mean the line segments, but just don't know math well enough to express yourself properly?
