3.15 Pocket milling with islands - CYCLE73, CYCLE74, CYCLE75
3.15.1 Transfer pocket edge contour - CYCLE74
Pocket milling with islands is an option and requires
SW 5.2 in both the NCK and MMC 103.
CYCLE74 (_KNAME, _LSANF, _LSEND)
Cycle CYCLE74 transfers the pocket edge contour to
pocket milling cycle CYCLE73. This is done by creating
a temporary internal file in the standard cycles directory
and storing the transferred parameter values in it.
If a file of this type already exists, it is deleted and set
For this reason, a program sequence for milling pockets
with islands must always begin with a call for CYCLE74.
Name of contour subroutine of pocket edge contour
Block number/label identifying start of contour definition
