Thanks for your replies! Both are good solutions to my question. More specifically, I am using the finish flowline spiral cutting method to cut a taper on the outer surface. Any idea on how to make the spiral start a bit higher than actual part? I've been able to do it by lying to it and drawing the part to be bigger than the actual part but was wondering if there was an easier way to do this. Thanks!

Hello, Does anyone know how to create a lead in/lead out for flowline in Mastercam? Thanks!

Thank you for your reply. I'm using a wheel with a radius and was hoping that the top part of the radius wheel edge would cut the undercut. Rough/Pocket seems to go all around the part because there are no check surfaces allowed. I've attached a screenshot. Thank you.

Hello! I am trying to make a rough cut pass using Surface Rough Flowline. The part is a convex cylinder. However when I have Check Flowline Motion for Gouge checked in Cut Control, the toolpath only shows for the top half of the part stopping at the midpoint. I'm thinking that it doesn't like the undercut but when I uncheck the Check Flowline Motion for Gouge box, it does a completely different toolpath which leaves a flat surface instead of the desired convex cylindrical surface. Thanks!
