Abstract

This paper presents simulation and analysis of machining of elastomers under cryogenic condition using finite element method. The inelastic-plastic finite element technique is established in this learning to examine the consequence of the single point cutting tool rake angle on the chip flow and cutting force developed in machined work piece during the orthogonal turning process of elastomer. The findings designate that an intensification in the tool rake angle leads to decrease in the cutting force developed and continuous and smoother chip contour during machining elastomer.
