Cutter comp in thread milling

[Roger]

I did my 1st thread milling tool path today. I've been programming with Mastercam since version 7, and today was the 1st day I have used the thread milling. I'm using X6, and used wear comp. But know D, or wear in the NC code. Anyone know why? I'm using the default mill post, and machine definition for a Haas VF5 SS mill.

You can only engage comp with a linear move.

Lead-In/Lead-Out should be a perpendicular line and an arc sweep of at least 22.5 degrees.

Entry line is grayed out. I know to use a entry line with a lead in, out. Even if you don't, MC still post the code with the (D), just errors out on most machines.

 

Please see the attached file from the help menu in MC. (I'm still confused on why no cutter comp in NC code).

[Guyinthedesert]

on the cut parameters page, have you selected "Wear" as compensation type?

 

On the lead in page, just select perpendicular entry. and start at center. The entry line length box is ungrayed when you uncheck Start at center. (Generally only used on large holes)

My fault! Thanks Tim!!! (Put a check mark in "Perpendicular entry")

More good to know info from Guyinthedesert! Thank you also!
