Mastercam X6 Preview #3 - Better Hybrid Machining

3D High Speed Machining “Filler” Passes
Over the next several weeks we’ll be drawing back the curtain on the upcoming Mastercam X6 and previewing some of the new features in the release. Today we'll focus on a new technique in a popular finishing strategy.
We had a lot of positive feedback on our hybrid finishing toolpath. We also got some suggestions on how to improve it and help deliver a better finish.  One such improvement is “filler passes” which now maintain all of the Z level cuts in steep areas of your part while filling in the shallow areas with scallop motion within a single Z section. It combines the best of both worlds with waterline (constant Z) motion and scallop where needed. In X5, shallow areas occasionally resulted in 3D collapse (essentially scallop) motion for all Z cuts at that level. Now you can have both waterline and scallop motion at the same Z section, section after section. The result is much better finish and more efficient use of the tool.

This illustration shows how hybrid machining can break a part into a series of Z "sections", each combining efficient waterline and scallop motion.
