Abstract
Near numerical control technology is the foundation of modern manufacturing technology, it iswidely used to make the ordinary machinery is replaced by CNC machinery, so that the global manufacturing industry has been a fundamental change. The level of numerical control technology, the degree of ownership and popularity has become a measure of a country's comprehensive national strength and an important symbol of the level of industrial modernization.
The task of this design is a typical shaft parts processing process design and programming, use of CAD drawing software parts of the two-dimensional graphics drawing out. Then for structural parts, precision, technical requirements are analyzed. Design and processing components of the NC process scheme, selection of blank, tools, machine tools, and the reasonable cutting parameters. Choose the best processing program, and the parts of the NC machining program is compiled, to complete the design.

Keywords: typical shaft; numerical control technology; processing technology; programming;
