摘要：This paper presents a 3D fractal investigation on ultrasonic vibration assisted end grinding surface of SiCp/Al composites. According to variational method, 3D surface fractal dimension is calculated with MATLAB software based on profile data, and evaluates the influence of process parameters on the surface quality. The experimental results indicate that 3D surface fractal dimension increases with spindle speed and vibration amplitude, and decreases with feedrate and cutting depth. A large value of 3D surface fractal dimension corresponds to a better surface finish.
