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.
Programming
FRC=... Non-modal feedrate for chamfer/rounding
Value > 0: Feedrate in mm/min (G94) or mm/rev. (G95)
FRCM=... Modal feedrate for chamfer/rounding
Value > 0: Feedrate in mm/min (G94) or mm/rev. (G95)
Modal feedrate for chamfer/rounding ON
Value = 0: Modal feedrate for chamfer/rounding OFF
Feedrate F applies to the chamfer/rounding
Notes
● F, FRC, FRCM are not active when a chamfer is traversed with G0. If the feedrate F is
active for chamfer/rounding, it is by default the value from the block which leads away
from the corner. Other settings can be configured via machine data
MD20201 CHFRND_MODE_MASK.
● A maximum of three blocks without corresponding information may be put between two
blocks containing traversing information for chamfer/rounding (axes of the plane). In the
case of more blocks without axis information in the plane and existing instructions for
inserting chamfer or rounding, an alarm is triggered.
