Research on the double-sided grinding and polishing machine tool system

Blades are one of the vital parts in devices such as aerospace engines and hydraulic turbines. The special working environment of these blades requires high quality and high surface roughness. In order to improve the anti-corrosion and anti-high-pressure performance of these blades, they are mostly manufactured by alloy materials which are difficult to be processed in production. In this paper, based on the study about common machining method for machining the blade surface, a new method for effectively finishing of blade surface by using a novel double-sided grinding and polishing machine tool is proposed. Firstly, the structure of this machine tool is designed and the machining process for a blade surface with this machine tool is described. Then the model of blade is constructed with reverse engineering method based on the measured data. At last, the tool path on blade is planned with the direction paralleled algorithm. Research work indicates that the designed double-sided grinding and polishing machine tool is practical in finishing of blade surface.
