How to start this part

[MBG]

Okay. I know how to program in the holes. I believe I am doing it right using a G81 canned cycle.


The question I have is how do I do the profile (exterior) of this part. Where do I start? I am thinking about using cutter comp.

Please led me in a right direction.


thanks a lot.

Do you have a cam package or are you just programming this manually? If you dont have a cam package it seems to me you have some trig to figure out before you start since the print doesnt list any angle dim.

I drew it up and dimensioned each of the end-points, and gave you a head start. Hopefully it makes sense and you can figure the rest.

Assuming .500" cutter diameter, climb cut leaving 0 stock (programmed manually quickly so please verify dimensions):

Okay. What did you exactly do here I don't follow.

Also, I don't need a Z axis programmed in there.


Also, where is your ZERO?

Not @ my computer, so short response. X0/Y0 is center of large radius. Lead-in at top right of part on angled line. Delete Z move if not needed. Hope this helps?

This may help. Check the lead-in and exit distance.
