What's newin version 16.4
- New: Rectangular pockets with a flat or round (U-shaped) floor. Rough programs for both, finish for flat only. - Blended chamfer: new concave bottom radius, set by depth or width. - Toolpath Check: edit the edit block and rerun in the app. - Export as .eia, .nc or .txt. - Programs use only #1–#32, so they run on older Mazaks. - Clearance is now measured from the side of the tool, not its center.
