Defining Round Profiling Tools in Lathe

[nofalloff]

I'm trying to set up a tool in lathe that has a round head for profiling. The tool Is a Sandvik Q-Cut with this insert: Button Head Insert The insert is in the default Sandvik insert lib in mastercam but only if you define the tool as a grooving tool. This seems to be causing problems with the lead in gouging. This is the first time I'm trying a cutter like this in Mastercam so I could have the parameters of the lead in set wrong. Right now setting the lead in to tangent seems to offer the most gouge free tool path. This seem like it should be pretty straight forward. what should I be look out for when using full round inserts in Mastercam for profiling? Is setting the tool up as a grooving tool part of the problem?

 

Thanks

I think I got it. Adding a small entry arc of 2.5x the DOC through 45deg is giving me a gouge free tool path. Now I need to see how it cuts.
