6.13 Recessing Cycles
Simple recessing cycle, axial G865 / radial G866
The cycles axially/radially machine the rectangle described by the tool
position and "X, Z."
Parameters
X base corner X (diameter value)
Z base corner Z
P recessing width
P is not defined: Infeeds <= 0.8 * cutting width of tool
P is defined: Infeeds <= P
I oversize X (default: 0)
K oversize Z (default: 0)
Q roughing/finishing
Q=0: Only roughing
Q=1: The recess is first rough-machined with consideration of the
oversizes and then finish-machined at finishing feed E.
E finishing feed rate or dwell time
For Q=0: Dwell time (for chip breaking)—default: Time of two
revolutions
For Q=1: Finishing feed—default: Active feed rate
Note on the execution of the cycle:
MANUALplus determines the cutting direction from the current tool
position relative to the starting point / end point of the contour area.
Tool position at the end of the cycle: Cycle starting point
