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.

Pre-positioning
Danger of collision!
The control does not automatically check whether collisions
can occur between the tool and the workpiece. Incorrect pre-
positioning can also lead to contour damage. There is danger of
collision during the approach movement!
Program a suitable pre-position
Check the sequence and contour with the aid of the graphic
simulation
Creating the NC blocks with the path function keys
The gray path function keys initiate the dialog. The control asks you
successively for all the necessary information and inserts the NC
block into the part program.
