Recessing and contour recessing
Recessing and contour recessing – Tool selection
Tool selection
Parameter Meaning
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)
Recessing and contour recessing – Oversizes
Oversizes
Parameter Meaning
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
32: Equidistant oversize –
No single oversizes
144: Longitudinal and
transverse oversizes differ –
With single oversizes
160: Equidistant oversize –
With single oversizes
Equidistant or longitudinal
KSLA
Equidistant oversize or longitu-
dinal 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 operation. A division
into rough-machining and finish-machining is only
possible in
