A Model of Cutting Forces for Ball End Mill in High Speed Machining

Abstract:

Article Preview

The machining characteristics of hardened still for mould and die greatly affect the accuracy and productivity in industry. The physical modeling and simulation of ball end milling is investigated in this paper. The influence of cutting speed to the cutting mechanism in high speed cutting is taken into account and the momentum force of chip is introduced into the model. By analyzing the shape of the chips the relationship between the cutting speed and shear angle is obtained. The model has been tested on 718HH, with appropriate Seco tools. The validation shows that the adjustment between the model and the real force is adequate, both in shape and magnitude.
