For example, Gates et al. (2008) have used ball mill abrasion tests (BMAT) to predict the relative service lives of wear-resistant alloys for grinding media in mineral grinding environments. The results showed that very hard (above 630 HV) martensitic steels and white cast irons only offer large performance benefits when grinding relatively ...

Methods of grinding and shaping the rear surface of hard-alloy polyhedral inserts are considered. Machining of the tool's rear surface is simulated, and several kinematic configurations for margin removal are proposed. An algorithm for kinematic shaping of the rear surface of a hard-alloy polyhedral insert in CAD systems is outlined.
