Toolpath Slashes Roughing Time
Mastercam/CNC Software, Inc. (Tolland, CT) offers OptiRough, a technique designed to remove large amounts of material quickly using dynamic milling motion.
OptiRough is a new technique designed to remove large amounts of material quickly using its successful dynamic milling motion. Large, aggressive cuts are followed by fast, smaller up-cuts, safely delivering a fully roughed part faster than ever.
Mastercam’s new 3D surface high speed OptiRough toolpath supports cutters capable of machining very large depths of cut.
A single OptiRough toolpath can cut material in two directions: on step-downs (-Z) and step-ups (+Z). This highly efficient, bi-directional cutting strategy removes the maximum amount of material with the minimum of step-downs, significantly reducing cycle times.
Below compares traditional roughing vs. OptiRough:
TOOLPATH TYPE CUTTERS # of TOOLPATHS TIME
OptiRough 1 1 00:05:17
Roughing Pocket 3 3 00:14:53
“The beauty of OptiRough is that you don’t need any special tooling to use it. It simply uses the tools you have now, but in a much more efficient way,” says Gary Hargreaves, VP, Business Development.

A lesson on shear induced melt variations ends some confusion regarding balancing runner systems for multi-cavity molds.
While both hot runner and cold runner systems have their benefits, for design flexibility as well as reduced cycle times and costs, hot runner systems will probably be the better choice.
