Download my sample file from CamInstructor. I have a swarf toolpath in that example that might help.

Without a sample file to see what your seeing going to extremely hard for anyone to know how to help. Do you have a floor surface checked? Are you using upper and lower edges? Are you using tilt lines? What is the normal of the surfaces if using surfaces and not solids? 

Ok great thanks for feed bk. I need to learn how to poat a sample file on this forum. I will do that and post it in the morning. Ill check out your video. I loved your 1st couple. Im checking that one out now. This project has me stuck at work trouble shooting.

I'm trying to clean up these walls with a 1/4 ball endmill. my tool keeps going thru my part and I'm not skilled enough yet to know why.  id like to get by with a little help from my friends

When it comes to facing all five sides of my block im creating planes for each face and chaining each one separately. Is there a beter way?

Great. Thanks for the feed bk. I acually stumbled upon by accident. I figuered if i have a plane do i need 5 axis. (Rookie at 5 axis, been playin with mills and mastercam for 15 years). Worked out great when i switched to 3 axis. Click click boom. Thanks for your input an wheel see ya a round.

I love to see arcs as much as I can. Am I forced to use small straight line on my 4 and 5 axis hole milling toolpaths?
