MC 2023 Lathe C-Axis Face Contour Verify issue

[David123]

Hi all

I am having some difficulty with C-Axis face contour toolpath. Operation 5 in the attached Mastercam file. When I back plot the toolpath I get sharp corners, however when I verify the toolpath it puts a chamfer on them. Maybe it’s a setting I am missing but I can’t locate it. Any help is greatly appreciated. 

Also, in verify why does the tool approach from the Z direction. This should be showing from the X direction. I know that the post will update the code to accommodate for it. It is a bit misleading. Is there a way to change this?

Regards

David

Your backplot is showing arcs moves on the corners and your verify result is showing sharp corners. To make the Backplot have sharp corners in Cut Parameters set "Roll cutter around corners" to "None". Typically you want it to roll around the corners. It is best to add chamfers or rads to your geometry to have the machine break the sharp corners instead of doing them by hand after the fact. 

The verify always shows the tool in that orientation.
