3.6 Tool and tool offset
Acute contour angles
If very sharp outside corners occur in the contour with active G451 intersection, the control
system automatically switches to transition circle. This avoids long idle motions.

Example of tool radius compensation (grinding)

The wheel should have the contour shown in the figure. Dressing takes place from left to
right using MIRROR and G41
Caution: The workpiece zero (XWP) in wheel data must be -110 to be able to program the
contour in workpiece coordinates.
