Abstract

To improve the manufacturing quality, performance of the tool, optimum cutting conditions and cost reduction many industries and academic centers are looking for alternatives that help of a better understanding of the metal cutting process. One of these alternatives is the Finite element method. This paper presents simulation and analysis of machining of elastomers using Ansys/Ls-dyna. The inelastic-plastic finite element method is developed in this study to investigate the effect of the tool rake angle on the chip flow, von-misses stress, total energy and residual stresses developed in machined work piece during the precision orthogonal turning process of elastomer. The findings indicate that an increase in the tool rake angle leads to decrease in the stress developed, smoother chip contour and a decrease in the total energy of the machined work piece.
