Linear Slot On Face G - HEIDENHAIN MANUALPLUS 620 User Manual

Linear slot on face G791

G791 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.
Parameters
X Final point of slot in polar coordinates (diameter)
C Final angle. Final point of slot in polar coordinates (for angle
direction, see help graphic)
XK Final point of slot (Cartesian)
YK Final point of slot (Cartesian)
K Slot length referenced to center of cutter
A Slot angle (reference: see help graphic)
ZE Milling floor
ZS Milling top edge
J Milling depth
J>0: Infeed direction –Z
J<0: Infeed direction +Z
P Maximum approach (default: total depth in one infeed)
F Approach feed (infeed rate) (default: active feed rate)
Parameter combinations for definition of the end point: see help
graphic
Parameter combinations for definition of the milling plane:
Milling floor ZE, milling top edge ZS
Milling floor ZE, milling depth J
Milling top edge ZS, milling depth J
Milling floor ZE
Rotate the spindle to the desired angle position before
calling G791.
If you use a spindle positioning device (no C axis), an
axial slot is machined centrically to the rotary axis.
If J or ZS is defined, the tool approaches to safety
clearance in Z and then mills the slot. If J and ZS are not
defined, the milling cycle starts from the current tool
position.
