Choose the correct methods for processing, processing process design reasonable. In addition, processing of a procedure of Supporting foot parts of the design of the fixture. Many types of machine tool fixture, wherein, universal fixture used the most widely, size has been standardized, and professional factory production. But widely uses in the volume production, specially for a special fixture workpiece machining process service, then needs various manufacturing plant according to the workpiece processing technology to design and manufacture. The main content of this paper is the design of Boring fixture design Supporting foot design.
