0612 Predicting the Springback of Metal Cutting Operations Using Mesh Free Methods

Abstract

The metal cutting process remains one of the most widely used methods in manufacturing. Computer simulations of metal cutting are a valuable tool to understand the physics involved and to predict the outcome of such processes. One of the most important results of such simulations is the prediction of process forces. However, there is a general trend of the normal forces being underreported, independent of the numerical method chosen. Supposed factors which affect the normal forces are the material compression underneath the rounded cutting tool edge and the springback accompanied by the compression. The focus of this work is thus to simulate the process forces and the springback employing mesh free methods. The results are verified using experimental data. Predicted process forces and springback show good agreement with the experimental data.
