Hello everyone, I have a little beginner problem with some parts i'm machining, they have a hole of 1.258 +0.002 -0.0. i use circle Mill on mastercam to rough and another seperate circle mill toolpath to finish with an M01 between the two, Now the problem i have is that the hole is not completely circular, i measured many different values ranging from 1.250 to 1.265 in the same hole. i try to change my offset to get the right tolerances but it can't seem to have one value when measures, i used my Lathe to create a kind of Go/Nogo, to quickly verify my parts, the go side has 1.255'' and the no Go has 1.563''. can i just rely on weather the go enters or not? or is my go way too small to give the right readings? On a seperate question concerning machining tolerances, i have had to machine a part like the one in the picture with a tolerance of 0.003'', but as you see the space walls are too long, so i can't have only one constant measurement between the walls all along them. (PS: the units of the drawing are in millimeters)

that's another problem i have, when i go on canned text, ihave no texts to add, is there a place i can go look for them on the computer? and what does 'force tool change' really do?

okay, if that's the way to do it then, i'll get to it. thanks

Hello everyone, this is gonna be my first post ever so bear with me if you find my question kind of obvious. Is there a way to stop the machine before it does the finish pass? i'm using 2D pocket for an open pocket and i use the finish option in the toolpath on which i added a wear control. i was wondering how can i add a M01 within the operation to verify the amount of wear i should add? should i create a new toolpath just for the finish and add a manual entry between the two or is there a way to do it in the same toolpath. thank you for your help.
