O: Hide undercutting
0: No
1: Yes
B: Slide mov.diff. – slide lead with 4-axis machining (not yet
implemented)
B = 0: Both slides work on the same diameter—at double feed
rate
B < 0: The slides work on different diameters at the same feed
rate. The slide with larger number leads at a defined distance
B > 0: The slides work on different diameters at the same feed
rate. The slide with the smaller number leads at a defined
distance
RH: Wrkpc. blank contour – evaluation only if no workpiece blank
has been defined
0: (depends on defined parameters)
No parameters: workpiece blank from ICP contour and tool
position
XA and ZA: workpiece blank from ICP contour and starting
point of workpiece blank
J: workpiece blank from ICP contour and equidistant
oversize
1: From tool position (workpiece blank from ICP contour and
tool position)
2: With blank start point (workpiece blank from ICP contour
and starting point of workpiece blank XA and ZA)
3 Equidistant oversize (workpiece blank from ICP contour and
equidistant oversize J)
4: Long.-transv. oversize (workpiece blank from ICP contour,
transverse oversize XA and longitudinal oversize ZA)
J: Workpiece blank oversize (radius value – active only if no
workpiece blank has been defined)
XA, ZA: Start point blank (definition of corner point of workpiece
blank contour – evaluation only if no workpiece blank has been
defined)
The control uses the tool definition to distinguish between external
and internal machining.
The tool radius compensation is active
A G57 oversize enlarges the contour (also inside
contours).
A G58 oversize
>0: Enlarges the contour
<0: Is not offset
G57/G58 oversizes are deleted after cycle end
