Modern machine tools and controls are help to perform machining processes better and more efficiently. Interruptions and failures due to software crashes have to be avoided in order to ensure high productivity.

The software option DCM—dynamic collision monitoring—offers optimal protection. DCM cyclically monitors the working space of the machine for possible collisions with machine components. The control interrupts machining whenever a collision is imminent, thereby increasing safety for the machine and its operator. This helps to prevent machine damage, which can result in costly downtimes. Unattended shifts become safer and more reliable.

However, DCM works not only in automatic mode. It is also active in manual operation. If, for example, during setup the machine operator takes a collision course, the TNC 640 detects it, stops axis movement, and issues an error message.
