New High Speed Toolpaths
In Mastercam X7, 3D HST Hybrid toolpaths include a new Optimize cut order checkbox which defines the cut order Mastercam applies to different cutting passes in the toolpath. When selected, Mastercam works in tiers, ordering the toolpath’s cutting passes based on proximity and safety. Mastercam machines features by area until it reaches a common Z-level, then repeats the process until it reaches the next common ground. The tool stays in a common ground, which reduces unnecessary motion and shortens the length of the toolpath.
Hybrid toolpaths now offer additional options for handling open and closed contours. Closed contours contain continuous motion without a need for a retract or reversal of direction. You can select climb or conventional machining for these contours. Open contours offer One Way or Zigzag cutting options. Open contours set to One Way will use the cutting method selected for closed contours.
The new Automatic Offset method controls how Mastercam handles the boundaries between steep and shallow areas. If the toolpath engages part surfaces that include core and cavity properties, Mastercam applies upper to lower offset methods to core features and lower to upper offset methods to cavity shapes.
The 3D HST toolpaths now calculate more efficient high speed motion at your part’s boundaries. To improve regeneration speed, they now only recalculate the necessary sections of the toolpath instead of processing the entire toolpath when changes are made.
The 3D HST Project toolpath projects either geometry or a toolpath from an earlier operation onto surfaces. Previously, the Project toolpath was only available as a surface roughing toolpath. In Mastercam X7, the full suite of high speed toolpath parameters are available to refine the tool motion.
