Feedrate for chamfer/rounding FRC, FRCM
The machining conditions can change significantly during surface transitions to chamfer/rounding. The chamfer/
rounding contour elements therefore need their own optimized feedrate values in order to achieve the required
surface finish.
You can program the feedrate for the chamfer/rounding with
FRC
(non-modal) or
FRCM
(modal).
Non-modal feedrate FB
A separate feedrate can be specified for an individual block with the
FB
command. The earlier active path
feedrate is overwritten for this block; the earlier effective modal path feedrate is active again after this block.
Programmable single­axis dynamic response
The dynamic response of individual axes can be changed in a targeted manner via programming.
• Percentage acceleration override (
ACC
) in part program and synchronized actions
• Programmable end of motion criterion:
FINEA
(exact stop fine),
COARSEA
(exact stop coarse),
IPOENDA
(Interpolator stop) in the part program and in synchronized actions
• Programmable servo parameter set (
SCPARA
) in the part program and in synchronized actions
