Generally valid constraints:
The
Dynamic Collision Monitoring (DCM)
function
helps to reduce the danger of collision. However, the
control cannot consider all possible constellations in
operation.
The control can only protect those machine
components from collision that your machine
tool builder has defined correctly with regard to
dimensions, orientation and position.
The control can only monitor tools for which you
have defined
positive tool radii and positive tool
lengths in the tool table.
When a touch probe cycle starts, the control no
longer monitors the stylus length and ball-tip
diameter so that you can also probe collision objects.
For certain tools (such as face milling cutters), the
radius that would cause a collision can be greater
than the value defined in the tool table.
DL
and
DR
tool oversizes from the tool table are
taken into account by the control. Tool oversizes from
the
TOOL CALL
block are not accounted for.
