Tool Breakage/Tool Wear Monitoring; Spindle Load Monitoring - HEIDENHAIN ITNC 530 - 6-2010 DIN-ISO PROGRAMMING User Manual

Tool breakage/tool wear monitoring

This feature must be enabled and adapted by the machine
tool builder. Refer to your machine tool manual.
With the breakage/wear monitor, a cut-based tool breakage detection
during active AFC can be realized.
Through the functions that can be defined by the machine tool builder
you can define a percentage value for wear or breakage detection with
respect to the rated power.
When the defined limit spindle power range is not maintained, the
TNC conducts an NC stop.

Spindle load monitoring

This feature must be enabled and adapted by the machine
tool builder. Refer to your machine tool manual.
With the spindle load monitoring function you can easily have the
spindle load monitored in order, for example, to detect overloading the
spindle power.
The function is independent of AFC, i.e. it is not cut-based and does
not depend on teach-in steps. Through the functions that can be
defined by the machine tool builder, you only need to define the
percentage value for spindle limit power with respect to the rated
power.
When the defined limit spindle power range is not maintained, the
TNC conducts an NC stop.
