Recessing, contour recessing – Tool selection, oversizes
Approach/departure strategy:
 1: Move simultaneously in X and Z directions
 2: First X, then Z direction
 3: First Z, then X direction
 6: Coupled motion; X precedes Z direction
 7: Coupled motion; Z precedes X direction
Approach and departure
Tool selection, oversizes
Recessing width divisor [SBD]
If a recess base machined with a contour-recessing cycle does
not contain paraxial elements but only linear elements, a
suitable tool is selected using the "recessing width divisor
SBD."
SB <= b / SBD
(SB: width of recessing tool; b: width of machining area)
Type of oversize [KSAA]
The recessing area to be machined can be assigned oversizes.
When oversizes have been defined, a recess is first rough-
machined and then finish-machined. Inputs:
 16: Longitudinal and transverse oversizes differ – no single
oversizes
 144: Longitudinal and transverse oversizes differ – with
single oversizes
 32: Equidistant oversize – no single oversizes
 160: Equidistant oversize – with single oversizes
