Computer simulation of the two body abrasive wear process.

Abstract

New computer technologies are applied to the classical material engineering two-body abrasive wear process. The computer simulation provides an interactive and visual representation of the wear process. The influence of grit size, grit tip radius and load (at constant workpiece hardness and tool path) on the wear rate, wear coefficient and wear surface topography is predicted. The simulation implements microcutting and microploughing with material displacement to the sides of the groove. The validation of the simulation is demonstrated by comparing with the previous modelling literature and with experiments.
