High-Speed Machining (HSM): Waveform and iMachining Toolpath Algorithms

Extending Tool Life While Tripling Material Removal Rates

Traditional roughing toolpaths took shallow cutting depths with high radial engagement, causing tool chatter and premature wear. High-Speed Machining (HSM) cuts using full tool flute depths with thin, constant radial step-overs.

The Mechanics of Constant Chip Load

Advanced toolpath algorithms adapt dynamically to sharp corners and changing part contours.

  • Avoiding Corner Spikes: Trochoidal peeling loops prevent cutter binding when machining tight internal pocket corners.
  • Constant Cutting Temperature: Consistent chip loads eject heat into flying chips rather than into the tool or workpiece.
  • Cycle Time Reductions: Specialized strategies like SolidCAM iMachining reduce roughing cycle times by up to 70%.
