Research on Fixture Design of NC Machine Tool Based on UG 3D Modeling

Research on the design of CNC machine tool fixture based on UG 3D modeling; Firstly, the processing procedure of the back cover parts is analyzed, and the overall scheme of the fixture is determined. Then the three dimensional model of each part of the jig is established including the standard part library of jig and the design of non-standard parts of jig. Then carry on the fixture 3D assembly drawing design; Finally, it is converted into fixture technical document including assembly drawing and specific part drawing. The design process is simple and clear, which improves the quality and efficiency of fixture design.
