Protection zones
3.3 Checking for protection zone violation, working area limitation and software limits (CALCPOSI)
Example
In the example (refer to the diagram), X software limits and working area limits are shown.
In addition, three protection zones are defined, the two channel-specific protection zones C2
and C4 and well as the NCK protection zone N3. C2 is a circular, active, tool-related
protection zone with a radius of 2 mm. C4 is a square, pre-activated and workpiece-related
protection zone with 10 mm side length and N3 is a rectangular, active protection zone with
10 mm and 15 mm side lengths. In the following NC, initially, the protection zones and the
working field limits are defined as sketched, and the CALCPOSI function is called with
various parameter assignments. The results of each individual CALCPOSI call are
summarized in the table at the end of the example.
