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

NOTICE

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
