Based on the key process of manufacturing flat-end cutter,the paper analyzes the optimization variables under different grinding methods. The method of establishing parameters optimization objective functions for different grinding methods of the flat-end cutter process was proposed and a grinding optimization model aiming at improving the grinding efficiency was established. Taking the axial relief angle grinding step for example,orthogonal experiments were designed and linear-regression analysis was used to fit the formula of grinding surface roughness. Then genetic algorithm and complex method are used to solve the model and verify it. The model may recommend optimized parameters for the grinding flat-end milling process.
