Collision monitoring in the
Test Run
operating mode
In the
Test Run
operating mode, you can perform collision
monitoring of an NC program prior to execution. The control stops
the simulation in case of a collision and displays an error message
indicating the two objects that would cause the collision.
If you have selected a screen layout in which the collision objects
are on the right, then the control additionally marks the colliding
objects in red.
Please note in
Test Run
operating mode
To obtain a simulation result that is similar to execution, the
following aspects must match:
Preset
Basic rotation
Offsets of each axis
Tilting condition
Activated kinematic model
In a simulation, the following aspects may differ from the actual
machine or may not be available at all:
The simulated tool change position may differ from the one in
the machine operating mode.
Changes in the kinematics may have a delayed effect in the
simulation.
PLC positioning movements are not displayed in the simulation.
Global program settings and handwheel superimposition are not
available.
Pallet processing is not available in the simulation.
HEIDENHAIN recommends the use of Dynamic Collision
Monitoring (DCM) in the
Test Run
operating mode only as an add-
on to collision monitoring in the machine operating mode.
Note the general limitations of the
Dynamic Collision
Monitoring (DCM)
function.

Activate collision monitoring in the simulation
To activate Dynamic Collision Monitoring in the
Test Run
operating mode, proceed as follows:
Select the
Test Run
operating mode
Press the
Collision Monitoring ON
soft key
You can toggle collision monitoring only after the simulation has
been stopped.
