Intelligent machining
– Dynamic Collision Monitoring option (DCM)
The complex motions and high traversing
speeds of five-axis machining make axis
movements difficult to foresee. This makes
collision monitoring a valuable function that
relieves the machine operator and protects
the machine from damage.
NC programs from CAM systems may
avoid collisions of the tool or tool holder
with the workpiece, but unless you invest
in expensive offline machine simulation
software, they ignore the machine
components located within the work
envelope. And even then it cannot be
guaranteed that machine conditions, such
as the fixture position, will be identical to
those of the simulation. In the worst case,
a collision will remain undetected until the
damage is done.
In cases such as these, the machine
operator is supported by the dynamic
collision monitoring (DCM)* feature of
the TNC 640. 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.
* These functions must be implemented in the
machine and TNC by the machine tool builder.
