Activating collision avoidance

With the aid of collision avoidance, you can avoid collisions and therefore major damage during
the machining of a workpiece or when creating programs.
Collision avoidance is based on a machine model (kinematic chains). The kinematics of the
machine are described as a kinematic chain. For machine parts to be protected, protection
areas are attached to these chains. The geometry of the protection areas is defined using
protection area elements. The control then knows how they move in the machine coordinate
system depending on the position of the machine axes. You then subsequently define the
collision pairs, i.e. two protection areas which are monitored with respect to one another.
The "Collision avoidance" function regularly calculates the clearance from these protection
areas. When two protection areas approach one another, and a specific safety clearance is
reached, an alarm is displayed and before the corresponding traversing block, the program is
stopped and/or the traversing motion is stopped.
