In the production process so that the production target (of raw materials, blank, or assembly of parts, and so on) the quality and quantity of the state direct the process of change is called process, such as blank manufacturing, machining, heat treatment, assembly, have called the process Process. In the course of the development process, it is necessary to determine the process to install the work place and the process needed further work, the process of the processing machine tools and otives of the feed rate, cutting depth, cutting speed and spindle speed, the process of the fixture, and cutting tools Measuring, and cutting the number and length of the knife away, the final calculation of the basic processes of time, support time and work to serve the time. As said by the given production package and part of the structural physiognomies and precision requirements. Grow technology solutions for process controls, draw and fill prehensive card processing, Depending on the size and positional accuracy of the holes of the request, determine positioning reference and positioning. Holding mechanism design, guide mechanism, drawing fixture assembly diagram, and the demolition of the main parts diagram drawing fixture. key words: Process Technology Step Allowance Orientation Program ??????????? 194535455 ????……………………………………………………………………………………… 1 1. ???????????......................................................................................... 3 ????????.........................................................................
