Tooling System for Diamond Turning of Hardened Steel Moulds with Apsheric or non Rotational Symmetrical Geometries

摘要

The direct machining of hardened steel, conventionally not possible due to high tool wear, can be enabled by applying an ultrasonic assisted process. In this publication a unique system, working with a frequency of 80 kHz will be applied to manufacture industrially relevant geometries in order to prove the potential of the process.
