12.32.14 Example on a double-slide turning machine
On the example of a double-slide turning machine, let us look at the configuration of collision
monitoring with a total of five protection zones.
The input resolution is: 10 -3 mm
The safety distance of a protection zone around the machine part is defined as 2 mm.
Slide 1 is moved through axes X1 (=1st axis) and Z1 (=2nd axis).
Slide 2 is moved through axes X2 (=3rd axis) and Z2 (=4th axis).
Slide 1 machines in front of, slide 2 behind the turning center. This results in two coordinate
systems with the respective machine zeros M1 and M2 (M1=M2).
The X coordinate of the 2nd machine coordinate system is mirrored with respect to the X
coordinate of the 1st machine coordinate system.
