Abstract

A partially constrained Eulerian finite element model for orthogonal machining with chip control tools is described. A new constrained free surface algorithm was developed in which the chip thickness was constrained to be uniform along the length of the chip. Using the model, the deformed chip shape and thickness, chip-tool contact, and the velocity, strain, stress, and temperature distributions can be determined. Simulations for machining of stainless steel 304 (SS 304) with obstruction and groove tools are presented. Good agreement was found, between measured and predicted tool forces and chip thicknesses.
