In this paper a mechanistic force model for contour turning is presented. Analytical solutions are developed for evaluation of the mechanistic parameters (chip load, chip thickness, chip width, effective lead angle), as a function of the process parameters (tool geometry, workpiece geometry, and the tool path). The effect of these parameter variations on the cutting forces is analyzed. Simple straight turning tests are employed for model calibration. A workpiece with convex and concave contours is employed for model validation. Model simulations are found to match well with the experimental results. The analytical model is utilized to investigate the effect of process variables with a full factorial design. [S1087-1357(00)01602-6]
