“…Bhattacharyya et al [2] studied the performance of ceramic cutting tools for machining of cast iron and found that mixed oxide ceramics give better performance compared to pure oxide and nitride ceramics. They found that the dominant wear mechanisms are attrition and diffusion, attrition dominating at slower speeds and diffusion at higher speeds.…”

“…Bhattacharyya et al [6] performed turning experiments of three different grey cast iron alloys (G14, G17, and G20) using pure alumina ceramic, alumina mixed ceramic, and Sialon (silicon nitride-based ceramic) tools. In the experiments with pure alumina ceramic tools with cutting speeds below 300 m/min, the attrition wear mechanism was predominant.…”

In machining processes, tool performance is measured by the tool life, which is determined by the tool wear rate. This rate is strongly dependent on the tool wear mechanisms that occur in a specific process. Moreover, determining the wear mechanism is a fundamental task for the development of cutting tools. However, the tool wear mechanism depends on factors such as the workpiece material, the cutting operation, the properties of the tool material, the cutting conditions, and the cooling/lubrication system. This study aims to contribute to the understanding of the mechanisms that cause wear in tools. First, it presents a review of the literature describing the wear mechanisms that are present in metal cutting. Then, an analysis of the tool wear mechanisms during the machining of steels and stainless steels using different cutting tools is presented based on a review of studies performed mostly by research groups at the University of Campinas and Federal University of Uberlandia, Brazil. This analysis was performed using pictures of the worn regions taken in a scanning electronic microscope (SEM) with energydispersive spectroscopy (EDS) device which are fundamental to better understand the causes of tool wear. The major findings of this work were as follows: (i) Attrition is a very important wear mechanism in the machining of ductile materials such as steels and stainless steels; (ii) when a steel alloy with high ductility and work hardening rate is machined, a hard burr occurs in the end of the depth of cut and the burrfurrowing effect on the tool coating stimulates the attrition mechanism; and (iii) other wear mechanisms like abrasion and diffusion also appear in the machining of steels and stainless steels.

“…Bhattacharyya et al (1989) analyzed the diffusion and attrition mechanisms which occurred in the continuous turning of cast irons, using three kinds of ceramic tools: pure, mixed and Sialon. When pure ceramic was used with cutting speed below 300 m/min, the wear was caused by attrition.…”
