Figure 2-16 Example for selecting TRC with KONT or NORM in front of and behind the contour

• KONT and G450/G451 (corner behavior at outer corners) has a general effect and

determines the approach and retraction behavior with TRC.

• When tool radius compensation is deselected, the retraction behavior is determined by

the NORM/KONT instructions.
