Boron-doped monocrystalline diamond as cutting tool for temperature measurement in the cutting zone

Abstract

Ultra-precision machining is a key technology for manufacturing optical surfaces in a broad range of automotive and aerospace applications. At the state of the art, no precise methods for analysing the temperatures in the cutting zone of a monocrystalline diamond tool are available. Precise cutting temperatures are required for a detailed analysis of the wear behaviour. High response times and low measurement accuracies are still challenges. In this work, a new approach for a precise temperature measurement using boron-doped diamonds is shown. The sensor properties of boron-doped diamonds were analysed and experimental investigations to show the suitability were carried out. First results show a great potential as measurement method for real time temperatures during the cutting process.
