Improved prediction of cutting forces via finite element simulations using novel heavy-load, high-temperature tribometer friction data

Prediction of forces in cutting operations is a valuable asset to manufacturers. This paper demonstrates the improvements in force prediction achievable in finite element simulations of orthogonal cutting with the incorporation of temperature-dependent friction data obtained from a custom heavy-load, high-temperature tribometer. The tribometer employed is briefly described and its similarities to tool-chip contact in cutting discussed. …
