The grinding limit or minimum particle size can be calculated from intercrystalline material parameters as described by Knieke et al. [55].The compression strength σ CS is a material parameter, and was used based on the assumption that compression is the dominant type of stress in a stirred media mill. The compression strength and minimum particle size are roughly correlated with each other ...

A typical application is to use a ball end mill to process femoral parts made of cast cobalt chromium alloy on a 5axis milling machine. High speed profiling strategy and high performance end milling cutter eliminate the grinding process. As a result, the machining cycle of each part is 11 minutes, which is 50% shorter than the previous method.
