11.2 Dynamic Collision Monitoring
(Software Option)
Function
The Dynamic Collision Monitoring (DCM) must be
adapted by the machine manufacturer for the TNC and for
the machine. Refer to your machine tool manual.
The machine manufacturer can define any objects that are monitored
by the TNC during all machining operations and even in the Test Run
mode. If two objects monitored for collision come within a defined
distance of each other, the TNC outputs an error message during test
run and machining.
The TNC can display the defined collision objects graphically in all
machining modes and during test run (see "Graphic depiction of the
protected space (FCL4 function)" on page 333).
The TNC also monitors the current tool with the length and radius
entered in the tool table for collision (assuming a cylindrical tool).
Provided that you have defined a separate tool holder kinematic
description for the respective tool, including a collision body
description, and have assigned it to the tool in the KINEMATIC
column, the TNC monitors this tool holder also (see "Tool-carrier
kinematics" on page 166).
Also, you can integrate simple fixtures in the collision monitoring (see
"Fixture Monitoring (Software Option)" on page 335).
