AI Technical Summary

Problems solved by technology

At present, milling and grinding (milling) semi-finishing processes are mainly used in the process of high-precision complex curved surfaces before polishing and finishing. Traditional milling and grinding processes mainly rely on manual operations by skilled workers, which is labor-intensive and efficient. Low quality, unstable quality, the existing milling and forming machine tools have high rigidity, and the coupling problem of milling force and milling cutter head position control has not been well solved. Moreover, in the milling process, especially in the grinding process, The milling cutter head and the workpiece are always in contact, and the grinding fluid is difficult to enter between the cutter head and the surface of the workpiece to be processed, so that the grinding fluid reduces the cutting temperature and takes away the chips, and the abrasive particles in the grinding fluid participate in the cutting It is difficult to guarantee the surface quality and processing efficiency of the processed workpiece, and it is difficult to adapt to the development trend of modern complex surface manufacturing with high precision, high efficiency and low cost.
