Reference machining

During reference machining, the control determines the maximum
utilization and the total utilization (utilization sum) for each
monitoring zone. The determined values are used as reference
values. To calculate the limit values for a monitoring zone, the
control uses the determined reference values and the predefined
factors specified in the machine parameters.
During reference machining, the block scan feature is
not available.
Perform reference machining under the conditions in
which the parts will later be produced, for example, with
respect to feed rates, spindle speeds, and the type and
quality of the tools you will be using.
