18.5 Tool radius compensation 2D (TRC)
Sub-movements
There are maximum 4 sub-movements in case of soft retraction and approach with the
following positions:
● Start point of the movement P
● Intermediate points P
● End point P
Points P
to the parameters defined and the geometrical conditions.
On retraction, the points are traversed in the reverse direction, i.e. starting at P
at P

Parameters

The response of the smooth approach and retraction function is determined by up to 9
parameters:
Non-modal G code for defining the approach and retraction contour
This G code cannot be omitted.
● G147: Approach with a straight line
● G148: Retraction with a straight line
● G247: Approach with a quadrant
● G248: Retraction with a quadrant
● G347: Approach with a semicircle
● G348: Retraction with a semicircle
