I'm hoping to get some feedback on my machining strategy I used in MasterCam. The model I'm going to cut is called a "Last". It is a foot form for building a shoe. I support CAD/CAM tools for a very large athletic footwear company, getting this model was ease. I also did not want to bother the CAM engineers here at work with my stupid questions
Doing the finish cut in Mastercam was easy. I just found the Multiaxis menu and went with rotary4ax. The problem I am having is I don't see a multiaxis roughing routine.
What I did was to rough the part on the right side of the last and then on the left side of the last. I would just spin the 4th axis to 90 degrees and do one side then spin the axis to -90 and do the other side. I wanted to stop when the cutter got to the center axis, but Mastercam did not stop there. It went on down past center to the bottom of the material. What I did was to delete the tool path that was below the center axis for each side. See my pictures below.
Was this method acceptable or is there a much better way?
