Finite element modeling of the machining of non-ferrous metals

摘要

Optimization of conventional and high-speed cutting processes for various materials requires accurate prediction of pertinent physical information such as cutting forces and temperatures. A 2-d finite element model is described which is capable of simulating chip formation in metals. Results presented include continuous and shear loaclized chip morphologies; temperature and strain distributions throughout the chip, workpiece and tool; heat generation rates in both primary and secondary shear zones; and orthogonal cutting force components. Materials simulated include titanium, zinc and aluminum.
