Collision Avoidance - Siemens SINUMERIK 840D sl Turning Operating Manual

Collision avoidance

Collision avoidance allows you to avoid collisions and damage while machining a workpiece or
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 the program is stopped before the corresponding traversing
block and/or the traversing motion is stopped.
Note
The collision monitoring is only valid for single-channel machines.
