Implementation of a fast tool servo with repetitive control for diamond turning

The integration of a fast tool servo (FTS) with piezoelectric actuation on a diamond turning machine (DTM) is presented. The intent of this research is to monitor improvements in surface quality in the areas of surface roughness and waviness observed in the facing of an aluminum work piece. Performa...

Summary:The integration of a fast tool servo (FTS) with piezoelectric actuation on a diamond turning machine (DTM) is presented. The intent of this research is to monitor improvements in surface quality in the areas of surface roughness and waviness observed in the facing of an aluminum work piece. Performance is compared between the utilization of a polynomial controller with position feedback of the tool, a repetitive controller that uses position feedback of the tool in conjunction with position feedback of the spindle face via and eddy current probe, and legacy performance of the DTM with no active control methodology.
