Explanation of the parameters
For an explanation of the parameters _RTP, _RFP, and _SDIS, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
For an explanation of the parameters _DP, _MID, _FAL, _FALD, _FFP1, _FFD, _CDIR, _MIDA, _AP1, _AD, _RAD1, and
_DP1, refer to Section "Milling a rectangular pocket - POCKET3 (Page 197)".
_PRAD (pocket radius)
The form of the circular pocket is determined solely by its radius.
If this is smaller than the tool radius of the active tool, then the cycle is aborted and alarm 61105 "Cutter radius too large" is
output.
_PA, _PO (pocket center point)
Use the parameters _PA and _PO to define the pocket center point. Circular pockets are always dimensioned across the
center.
_VARI (machining type)
Use the parameter _VARI to define the machining type.
Possible values are:
Units digit:
●
1=roughing
●
2=finishing
Tens digit (infeed):
●
0=vertically to pocket center with G0
●
1=vertically to pocket center with G1
●
2=along a helical path
If a different value is programmed for the parameter _VARI, the cycle is aborted after output of alarm 61002 "Machining type
defined incorrectly".
Note
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.
Internally in the cycle, a new current workpiece coordinate system is used which influences the actual value display. The
zero point of this coordinate system is to be found in the pocket center point.
At the end of the cycle, the original coordinate system is active again.
