Grinding and grind-hardening process monitoring and control

DAN's Investigations have been done focused on the development of a control integrated monitoring strategy for the on-line characterisation of the grinding wheel status, in order to detect when the wheel requires dressing.

CNC integrated monitoring system has been developed based on the acquisition and processing of internal data provided by the CNC. Experiments have been carried out under different cutting conditions in a tangential grinding machine. The grinding wheel wear, part roughness, specific power consumption and process forces have been measured. Increasing energy consumption during successive grinding strokes is a suitable performance index to detect when the wheel requires dressing.

In the same way, the effects of vibrations during cutting on process signals, roughness and wheel wear evolution have been studied.
