Abstract In order to research the effect of process parameters on removal depth in the process of robot grinding epoxy coating on aircraft skin, a robot automatic grinding platform was built. According to Preston equation, the removal model of epoxy coating was established. The workpiece grinding process was simulated by Deform software and the influence of process parameters on removal depth under the single factor condition was studied. The regression mathematical model of removal depth and workpiece grinding test are established for theoretical analysis and verification. The results show that the removal depth is directly proportional to the grinding pressure and tool rotation speed, inversely proportional to the tool feed speed and abrasive particle size. Grinding pressure has great influence on removal depth, while tool rotation speed has relatively little influence on removal depth. During the grinding process, the uniform removal is realized by controlling the constant contact force and good surface quality is obtained.
