Finite element modeling approaches in grinding

Abstract. This paper presents a review of two-dimensional (2D) and three-dimensional (3D) finite element grinding models after 1995 and categorizes them by the scale of the modeling approach—either macro- or micro-scale. Macro-scale models consider the overall wheel–workpiece interaction while micro-scale models focus on the individualCompliant grinding and polishing refers to a class of fine material processing methods relying on one or more system element being compliant with the workpiece surface in a controllable and reversible manner, thus being distinct from conventional rigid wheel grinding and polishing. The resulting surface adaptability greatly Compliant grinding and polishing: A review ScienceDirect
