Abstract

Finite element method is an effective numerical technique which prove to very effective for analyzing problems of contacting surfaces such as chip morphology and process variables i.e. forces, temperature, stresses and strain .To study the effect of the factors such as spindle speed, depth of cut and feed rate on the material removal rate, for analyzing and prediction of the performance in machining process using ANSYS software. Great attention was targeted at investigating the equivalent stresses, strain and total deformation developed in the titanium work piece when cut by AISI 1045 turning tool. The equivalent stress on the workpiece was determined to be 1023Mpa. The simulation produced an equivalent (Von mises) strain of 2.5662mm. The workpiece sustained a total deformation of 6.108mm and 0.0000012mm as its maximum and minimum values respectively.
