Abstract: Since it is difficult for ultrasonic vibration compound machining to get effective
cutting mechanism mathematical model through dynamic analysis, and experimental study is
shown an effective method to solve this problem, following researches by means of central
composite design(CCD) testing are carried out. 4-factor and 3-level SiC wafer ultrasonic vibration
compound machining test scheme is designed, and then second-order relational model is
established between tangential cutting force, surface roughness, and their main process
parameters (wire saw speed, workpiece feed rate, rotational speed, and ultrasonic amplitude) by
using response surface methodology. According to multiple quadratic fitting of testing data,
quadratic equation of cutting force and surface roughness is obtained. Constrains of actual
machining condition upon the parameters are analyzed further. With the goal of improving
surface quality (minimized surface roughness) of SiC wafer, the parameters optimization model is
established. Particle swarm optimization algorithm and its procedure are designed to solve the
model. Test proves that the algorithm could achieve optimized process parameters which satisfy
multiple constraints rapidly and effectively. © 2013 Journal of Mechanical Engineering.
