Haas G187: Haas Smoothing/Precision Control

Adjust smoothing mode, precision, or path speed on compatible Haas controls.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.

G187 P... E...
  • Haas-specific; don't convert it directly to Fanuc/Siemens without reviewing the smoothing strategy.
  • P/E can affect finish, cycle time and corner accuracy.

Fanuc · Siemens

  • Fanuc: Partial equivalences depend on AI contour control, G05.1 or high speed functions installed.
  • Siemens: Partial equivalences depend on COMPCAD, CYCLE832 or dynamic path adjustment.
