Linear slot on lateral surface G792
G792 mills a slot from the current tool position to the end point. The
slot width equals the diameter of the milling cutter. Oversizes are not
taken into account.
Parameter combinations for definition of the end point: see help
graphic
Parameter combinations for definition of the milling plane:
 Milling floor XE, milling top edge XS
 Milling floor XE, milling depth J
 Milling top edge XS, milling depth J
 Milling floor XE

Parameters
Z
Final point of slot
C Final angle. Final point of slot (for angle direction, see help
graphic)
K Slot length referenced to center of cutter
A Slot angle (reference: see help graphic)
XE Milling floor
XS Milling top edge
J Milling depth
 J>0: Infeed direction –X
 J<0: Infeed direction +X
P Maximum approach (default: total depth in one infeed)
F Approach feed (infeed rate) (default: active feed rate)
 Rotate the spindle to the desired angle position before
calling G792.
 If you use a spindle positioning device (no C axis), a
radial slot is machined parallel to the Z axis.
 If J or XS is defined, the tool approaches to safety
clearance in X and then mills the slot. If J and XS are not
defined, the milling cycle starts from the current tool
position.
