Mastercam Lathe Concern

Recommended Posts

Psccomp should not generally be called from ltlchg$.

Mastercam outputs motion to the NCI file, with flags that trigger the Comp On/Off in the proper spot. There are also typically some MP Functions that are also involved in Compensation calculations.

Typically, psccomp, would get called on each motion line (Rapid, Feed, Arc CW, Arc CCW), and when the flag changes in the NCI, the Comp On will output on that specific line. Same with Comp Off.

Definitely a Post issue, but just wanted to caution you, in case you aren't very familiar with editing Posts. It is easy to break your Post badly, if you are messing with Comp, and don't really understand how to make the edits properly...

Our lathe post uses G53 for home positioning. It is a Siemens Control.

 

Is ther much you use mcam for over the Shopturn?

There were only 2 or 3 jobs where we couldn't get shopturn to do exactly as we wanted (because of the cycles) so we posted in mastercam and then entered the geo points in siemens circle/straight cycle which worked flawless as it kept the prog as a shopturn program
