Collision avoidance (only 840D sl)

12.1

Activate 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.
The collision avoidance is based on a machine model. The kinematics of the machine are
described as a kinematic chain, to which different protection areas for machine parts and tools
are assigned. With the help of collision pairs, two protection areas are monitored for collision.
The "Collision avoidance" function regularly calculates the clearance of these protection areas
during machining. When two protection areas approach one another, and a specific safety
clearance is reached, an alarm is displayed and the program before the corresponding
traversing block is stopped and/or the traversing motion is stopped.
Precondition
● Collision avoidance is setup and an active machine model is available.
● The setting "Collision avoidance" has been selected for the AUTO operating mode or for
the JOG and MDA operating modes.
