Modeling and simulation of stress for cemented carbide cylindrical end mill

The cutting force and stress of tool is important factor for failure of tool in the cutting process. Predictions of the forces and stress in milling are often needed in order to establish automation or optimization of the machining processes. A theoretical model for milling forces according to a predictive machining theory and the experiment of milling has been presented. The action of a milling cutter is considered as the simultaneous work of a number of single-point cutting tools, and milling forces are predicted from input data of the workpiece material properties, the cutter parameters and tooth geometry, and the cutting condition. Based on cutting force model, the stress of cemented carbide cylindrical end mill is developed. The numerical simulation and the experiment are performed to compare with stress model of mill. Milling tool stress experimental tests and numerical simulation separately were conducted to verify the simulation. The study provides a reliable method for analyzing stress of tool in the milling process.
