摘要：

This paper describes the wear patterns on hot filament HFCVD-diamond coated carbide and ceramic tools during the cutting process, as well as the origins of these patterns. Knowledge of these phenomena is essential for a process-oriented application and for a full exhaustion of the tool's potential. A focal point is put on the processes turning, milling, and drilling. Fiber reinforced materials, a hypereutectic aluminum-silicon alloy, and a copper-aluminum alloy are used. Closest attention is paid to the abrasive and adhesive wear on the coated tools and similarly on the uncoated substrate carbide. The results show that CVD diamond coated carbide and ceramic tools enlarge the existing range of cutting materials. The wear protective diamond layer suggests an application of the tools in the high-speed range (HSC). Given the demands for an environmentally acceptable production, these tools can be applied in dry machining. (C) 2000 Elsevier Science B.V. All rights reserved.
