Operation Manual

HEIDENHAIN CNC PILOT 640 575
8.2 Parameters
Recessing, contour recessing – Machining
Evaluation: DIN PLUS
Equidistant or longitudinal [KSLA]
Equidistant oversize or longitudinal oversize
None or transverse [KSPA]
Transverse oversize
 The oversizes are accounted for when machining
contour valleys with a contour-recessing operation.
 Standardized recesses such as recess types D, S, A are
completed in one machining cycle. A division into rough-
machining and finish-machining is only possible in DIN
PLUS.
Tool selection, oversizes
Machining
Recessing width factor [SBF]
SBF is used for calculating the maximum offset for recessing
cycles G860, G866:
esb = SBF * SB
(esb: effective recessing width; SB: width of recessing tool)
