Lathe groove rapid move crash

[wdg5555]

Was working on a file today and I noticed at the end of the grooving finish path that it rapids into the part. After messing around with mastercam trying to get it to not rapid into the part I ended up trying to change the 1st pass direction. After I did this it does not crash into the part anymore.

 

Attached is the file that shows the rapid move going into the part. Just wanted to know why so I can avoid crashes in the future.

 

Thanks!

I changed your second pass lead in to .15 and it did not gouge anymore, it looks to me that it is trying to go back to the first pass lead in depth. I don't think that you should be using a groove path for this feature, i would just do a contour.

Looks like that is the case. I'm ruffing it out with the grooving tool also. I just took off the roughing before I posted the file.
