Radius compensation
The radius compensation must be in the block in which you
move to the first contour element. You cannot activate radius
compensation in a circle block. It must be activated beforehand in
a straight-line block (see "Path contours - Cartesian coordinates",
page 216).
Pre-position
Danger of collision!
Before running a part program, always pre-position
the tool to prevent the possibility of damaging it or
the workpiece.
