Feedrate For Chamfer/Rounding: Frc, Frcm - Siemens SINUMERIK 802D sl Function Manual

24.1.4

Feedrate for chamfer/rounding: FRC, FRCM

Chamfer/rounding
You can insert the chamfer (CHF or CHR) or rounding (RND) elements into a contour corner.
If you wish to round several contour corners sequentially by the same method, use "Modal
rounding" (RNDM).
You can program the feedrate for the chamfer/rounding with FRC=... (non-modal) or FRCM=
... (modal). If FRC/FRCM is not programmed, the normal feedrate F is applied.

FRC=...
FRCM=...
Notes
● F, FRC, FRCM are not active when a chamfer is traversed with G0. If the feedrate F is
