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. 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.
