Rounding, chamfer
Fu n ctionality
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.
; Insert chamfer, value: Length of chamfer
; Insert chamfer, value: Side length of the chamfer
; Insert rounding, value: Radius of chamfer
Value >0: Radius of chamfer, modal rounding ON
This rounding is inserted in all contour corners.
Value = 0: Modal rounding OFF...
-modal feedrate for chamfer/rounding
lue >0, feedrate in mm/min (G94) or mm/rev. (G95)
; 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
lies to the chamfer/rounding.
The chamfer/rounding functions are executed in the current planes G17 to G19.
The appropriate instruction CHF= ... or CHR=... or RND=... or RNDM=... is written in the block with axis movements leading
to the corner.
The programmed value for chamfer and rounding is automatically reduced if the contour length of an involved block is
insufficient.
No chamfer/rounding is inserted, if more than three blocks in the connection are programmed that do not contain any
information for traversing in the plane or a plane change is carried out.
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.
