Another V9 lathe question

[lynnz]

I just uploaded a file to cadcam's site in the lath folder. it's named rough problem.mc9

The problem is the rough toolpath won't cut the selected profile completely down to centerline. (on rightside of part). if I shorten the profile to within .02" of centerline, then it will cut the face.

It used to work fine in V8 programming this way. It's probably something I have switched off or wrong.

Appreciate any input on this. We are not running solids with our lathe program.

 

Thanks

Lynn

Lynn,

 

I've tried a number of things on your part and was able to repeat the same thing with your file. There definitely seems to be something odd about this operation. I included a Semi-finish with 2 passes, at .03" step. This does rough the entire profile, even from the centerline. I recommend sending this file to your reseller and they can send it on to QC at Mastercam. QC will delete the file after they have examined it and found whatever isn't right. In the meantime, try the Semi-finish for roughing and see if that gives you what you need. HTH

Peter,

Thanks for looking at the file. This has us puzzled as we used to do this in V8. It's not the end of the world as we just added a facing cut to take care of the leftover material. But this has happened in about 3 or 4 other parts as well.

 

I have forwarded the file to my VAR and will stay tuned to see what QC says.
