Research And Design Of Grinding Wheel Shaping Machine Based On The Dynamic Simulation

Forming grinding, which is a modern processing methods which the CNC technology is used to achieve the ultimate processing workpiece machining requirements of the size only in a time grinding , usually directly determines the accuracy of the workpiece. Therefore forming dresser became one of the key factors in forming grinding. The purpose of this paper is to study and design a machine for grinding the surface of complex partsAccording to the actual use requirements of molding grinding wheel, designs of the function layout and analysis of the collectivity capability of the grinding wheel shaping machine are finished in this paper. As well as special analysis focused on improving this machine precision and overall structure .The object accuracy of the tool is analyzed emphatically, and the types and accuracy of key components are chosen.Secondly, The machining accuracy of work piece is influenced by the accuracy of the spindle and feed component. Therefore, based on the analysis of the several key elements of the spindle design , the advantages and disadvantages of several common main axis structures. The main axis structure of the machine tool is designed, and the feed component structure in accordance with the size of molding grinding wheel is designed also.Thirdly, by using ANSYS ,one of the large-scale general-purpose finite element analysis software, the finite element modelings are built and mechanical performance of the spindle parts and arbor components are analyzed. Then both of the structures are optimized according to the analysis results.Finally, experiment of testing on the performance of main shaft and arbor component by using vibration testing instrument during the processing has been produced. The experimental results show that the overall performance of machine tools meet the design accuracy requirements . and also prove that the design methods is practical...
