Simulation of Oblique Cutting in High Speed Turning Processes

A Finite Element Model is developed for Oblique cutting process in high speed turning of H-13 tool steel. The material model used for workpiece is elastic-thermoplastic including the strain rate sensitivity effect. In order to predict the tool performance, tool is considered as non-rigid and direct stresses are determined around the tool tip. Lagrangian approach is utilized along with adaptive meshing to minimize element distortion around the tool tip. The model predicts cutting forces in 3-directions at different inclination angles. The results are compared with experimental data and found to be in good agreement. The model is also able to predict stress and temperature contours in the workpiece and the cutting tool which help in predicting workpiece surface integrity and performance of the cutting tool.
