Research of the Virtual Prototyping and Simulating on Ultra-Precision Double-Sided Planar Polishing Machine

Abstract

Based on virtual prototyping technology, dynamic simulation of PE-1 type ultra-precision double-sided polishing machine and its technologic parameter optimization was studied. Through the simulation of virtual prototype, which was built in ADAMS, the polishing process was analyzed. Firstly, the simulation of polishing process shows that the ratio of rotation and revolution angular speed is inversely proportional to input speed ratio of planetary system. Secondly, the simulation of movement route shows that points along the same radius have similar route style considering the same input speed ratio of planetary system. Thirdly, the optimization of material removal non-uniformity shows that the higher speed makes for higher removal quality, the speed of solar gear and gear ring is opposite when the optimum value reached. At last, the maximum removal rate was achieved on the condition of same press and speed of plate, and corresponding solar gear speed and gear ring speed were gained.
