_FALD (finishing allowance)
When roughing, a finishing allowance in the depth is taken into account which is programmed under this parameter.
The residual material remained as the finishing allowance must always be specified for finishing to ensure that the tool can
be retracted and then fed to the starting point of the next cut without collision.
If > 0, the parameter is ignored for finishing.
Use the parameter _VARI to define the machining type.
Possible values are:
● Units digit:
1=roughing to finishing allowance
2=finishing
● Tens digit:
1=parallel to the first axis of the plane; unidirectional
2=parallel to the second axis of the plane; unidirectional
3=parallel to the first axis of the plane; with alternating direction
4=parallel to the second axis of the plane; with alternating direction
If a different value is programmed for the parameter _VARI, the cycle is aborted after output of alarm 61002 "Machining type
defined incorrectly".
A tool compensation must be programmed before the cycle is called. Otherwise, the cycle is aborted and alarm 61000 "No
tool compensation active" is output.
Programming example: Face milling
Parameters for the cycle call:
_RTP Retraction plane 10 mm
_RFP Reference plane 0 mm
_SDIS Safety clearance 2 mm
_DP Milling depth -11 mm
_PA Starting point of the rectangle X = 100 mm
_PO Starting point of the rectangle Y = 100 mm
_LENG Rectangle dimensions X = +60 mm
