Shorten Threadmill Program

[SpecialtyTool]

Im trying to program a 1/4-20 threadmill .250" deep with a form cutter, not a single point. MasterCam is posting a program with a line for each .001" it comes up in "Z".  Is there a way to get MasterCam to post a condensed code? I know a threadmill program written by hand is only a few lines.

 

Thanks

you need to change your control def to allow arcs

Also need to make sure your operation is not set to linearized arcs. Mastercam seems to think everyone loves to cut threads point to point. You all think I am crazy, but that is the default install.

same with ramp cutting

Thanks. That was a big help. Now my only concern is turning on cutter comp. Its been a while since I've messed with programming so please be patient. I thought typically you have to move 1/2 the cutter diameter to turn on cutter comp. but my tool is .180 diameter in a .201 hole...see the issue? When I try to backplot my toolpath it looks good except for the lead in and out

 

Thanks

You're not crazy.

Mastercam lathe posts still default to using an E address for threading feed in the default posts.

FANUC hasn't used an E for thread feed since the 6T.

 

For some context, here's a 6T control on an old Mori SL-2H
