tion (IWG)
Roughing transverse (G820)
The IWG generates the cycle G820 for the selected contour area.
“Roughing” soft keys
Longitudinal/constant oversize
FD relief turn machining
E and F undercut machining
G undercut machining
H, K and U undercut machining
Parameters
P Cutting depth (maximum infeed)
A Approach angle – reference: Z axis (default 90°/270°)
W Departure angle – reference: Z axis (default 0°/180°)
X Cutting limit
Z Cutting limit
I Depending on the soft-key setting:
„ Longitudinal oversize
„ Constant oversize (generates “Oversize G58” before the
cycle)
K Transverse oversize
Plunge-cutting (machine descending contours)?
„ Yes
„ No
E Reduced plunging feed rate with descending contours
H Type of departure (type of contour smoothing)
„ H=0: Machines contour outline after each pass
„ H=1: Retracts at 45°; contour smoothing after last pass
„ H=2: Retracts at 45° – no contour smoothing
Q Type of retraction at end of cycle
„ Q=0: Return to starting point (first X, then Z direction)
„ Q=1: Positions in front of the finished contour
„ Q=2: Retracts to safety clearance and stops
Undercut machining. The setting is made by soft key.
