Description
In Creo Parametric, the HSM Rough and HSM Rest Rough sequences now include new parameters for 3-axis and 3+2-axis machining.

• UPCUT_CUT_FEED and UPCUT_STEP_OVER—These parameters are applicable for the CONSTANT_LOAD scan type with the ZIG_ZAG or UPCUT cut type. Use these parameters to define less aggressive values of cutting feeds and step overs for the upcut passes instead of the STEP_OVER and CUT_FEED values.

• START_POINT_SHIFT_PERCENT—This parameter is applicable for TYPE_SPIRAL scan type. It shifts the start point of the next pass according to the specified percentage of stepover.

Benefits

• The UPCUT_CUT_FEED and UPCUT_STEP_OVER parameters provide the following benefits:
  • Better control on feeds for upcut passes
  • Reduced chattering marks and improved tool life
• The START_POINT_SHIFT_PERCENT parameter provides the following benefits:
  • Smoother entry to the next pass
  • Reduced cutting load on the tool
• Consistent with Creo NC workflows
