Purpose: This paper discusses improvements associated with the tool life of cutting tools used to machine alloy steels. To achieve this in an efficient manner, experiments on a variety of tool coatings are conducted on AISI M42 tool steel (58-63 HRC). Design/methodology/approach: In order to assess the impact of different tool coatings on machining process, initial experiments simulate current machining operations; this provides a benchmark standard for tool life and surface finish. Findings: The findings in the paper show that TiAlCrN and TiAlCrYN coated WC-Co cutting tools perform better than uncoated and TiN coated cutting tools. Research limitations/implications: The implications of the paper tend to indicate that dry machining of M42 tool steels can be optimized using coated cutting tools. The limitations of the paper include machining at specific cutting speeds and the employment of a short-time tool wear method. Practical implications: The practical implications of the paper show that dry machinig of hardened tool steels can be achieved under specific circumstances. Further research is needed to explain how the wear mechanism changes under various machining conditions. Originality/value: The paper presents original information on the characteristics of dry machining of tool steels under specific machining operations. The paper is of interest to manufacturing engineers.
