12.2 Dynamic Collision Monitoring
(option 40)
Function
Refer to your machine manual.
The machine manufacturer needs to adapt the
Dynamic
Collision Monitoring (DCM)
( D ynamic C ollision
M onitoring) function to the control.
The machine manufacturer can define any objects that will be
monitored by the control during all machining operations. If two
objects monitored for collision come within a defined distance of
each other, the control generates an error message and terminates
the movement.
The control can display the defined collision objects graphically in
all Machine operating modes and in the
Test Run
operating mode.
Further information: "Graphic display of the collision objects",
page 506
The control also monitors the active tool for collision and displays
the situation graphically. The control always assumes cylindrical
tools. The control likewise monitors stepped tools according to
their definition in the tool table.
Further information: "Indexed tool", page 243
The control takes into account the following definitions from the
tool table:
Tool lengths
Tool radii
Tool dimensions
Tool carrier kinematics
NOTICE
Danger of collision!
Even if
Dynamic Collision Monitoring (DCM)
is active, the
control does not automatically monitor the workpiece for
collisions, be it with the tool or with other machine components.
There is a danger of collision during execution!
