2.6 Dynamic Collision Monitoring
(Software Option)
Function
The machine manufacturer can define any objects that are monitored 
by the TNC during all machining operations. If two objects monitored 
for collision approach each other within a defined distance, the TNC 
outputs an error message.
The TNC also monitors the current tool with the length and radius 
entered in the tool table for collision (assuming a cylindrical tool).
The dynamic collision monitoring is active in all machine operating 
modes, and is indicated by a symbol in the operating mode display.
Collision monitoring in the manual operating 
modes
In the Manual Operation and Electronic Handwheel operating modes, 
the TNC stops a motion if two objects monitored for collision approach 
each other within a specified distance. In addition, the TNC reduces 
the feed rate significantly when the distance to the limit value 
triggering the error is less than 5 mm. 
There are three zones determining the TNC’s corrective behavior:
Early warning: Two objects monitored for collision are within 14 mm 
of each other
Warning: Two objects monitored for collision are within 8 mm of 
each other
Error: Two objects monitored for collision are within 2 mm of each 
other
The Dynamic Collision Monitoring DCM must be adapted 
by the machine manufacturer for the TNC and for the 
machine. Refer to your machine manual.
Please note that for certain tools (such as face milling 
cutters), the diameter that would cause a collision can be 
greater than the dimensions defined in the tool-
compensation data.
