CVD Coated Diamond Tools for the Machining of Lightweight Materials

Abstract:

The economic machining of materials used in the automotive and aeronautical industries, such as aluminium silicon alloys is often not possible without the use of superhard tools. CVD diamond coated tools have demonstrated their suitability for these applications in the past, however, the insufficient coating adhesion and thus tool failure remains an issue to date. Within the work presented here, two cemented carbide types were studied as substrates for CVD diamond coatings. Milling and turning tests were undertaken in order to assess the coating adhesion of the diamond tools. Furthermore, residual stress analysis was undertaken with the aim of understanding the impact of the coating and substrate residual stresses on the tool’s process performance.
