I am unfamiliar with the programming of mastercam and one of the items that my programmers constantly run into, is getting the material out of corners when doing complex 3-d shapes. The first roughing cutter might be 1/2 " ball leaving .01" stock. When we send in the next tool-lets day a 3/8 ball leaving .002 stock, the tool does well until it gets into the corner where it runs into the excess material from the 1/2 tool. Is there a cutter path that will pick at the remaining stock. gradually taking the excess out and still keeping the cutter engagement top the correct specifications.
