TRC option PERPENDICULAR_RADIUS_CHANGE

This option directly extends a programmed change in tool radius by inserting a motion orthogonal to the programmed contour.

Orthogonal extension of a tool radius change

Syntax:

#TRC [ [PERPENDICULAR_RADIUS_CHANGE=..] ]

PERPENDICULAR_
RADIUS_CHANGE=..

This parameter can extend the change perpendicularly if there is a change in tool radius.

0: No perpendicular extension of the new tool radius (default)

1: Perpendicular extension of the new tool radius

In the program examples, a change is made to the tool radius between the programmed motion blocks N50 and N60.

To illustrate the reaction, a very large change in tool radius is chosen. Normally, a change in tool radius involves very small corrections.

Several block transitions are shown in the examples below. All combinations of linear and circular blocks are permitted.
