Abstract

This paper presents a mechanistic model for the prediction of thrust and torque experienced by a forming tap during an internal thread forming process. The model relates the forces to the area of contact between the tool and the workpiece. Experiments are conducted to calibrate and validate the model. The model-predicted thrust and torque values compare favorably with the experimental values. Sensitivity analysis was conducted to examine the effect of relief and entry taper angles on the forces generated during the process.
