This paper presents several cutting models for cutting the workpiece of piecewise linear profile with abrasive grain of a trapezoidal rake face. They are designed for the purpose of good application in analysis of the grinding mechanism, and are developed from the cutting models with abrasive grain of a triangular rake face that are previously presented. An energy method is developed based upon their models, which enables to predict the deformation and the components of cutting force by using the data in orthogonal cutting under equivalent cutting conditions. Then the cutting force components F_H and Fv are measured and further the transition state between the models are observed by changing the inclination and normal rake angles of the tool and the workpiece profile of piecewise linear. The model tool, which has a trapezoidal rake face and is made of sintered carbide are used in turning experiment. And the cylindrical workpiece which has thread on the cylindrical surface is used. The measured results are in good agreement with the analytical results.
