The reasonableness, advanced components of its machining process , will directly affect the quality, production costs, the use of performance and longevity. Numerical control processing technology gets the traditional machinery manufacturing, computer technology, modern control technology, sensor testing technology, information processing and optical technology together，it is the foundation of modern machinery manufacturing technology. The widespread application of numerical control processing technology has brought about tremendous changes to production methods and product structure of the machinery manufacturing. numerical control processing is a method that uses numerical information to control the movement and processing of machine tools. numerical control processing technology incorporates numerical control processing and programming, metal machining, CAD/CAM operation sofeware, and other aspects of knowledge and experience, its main task is to calculate the tool points (short for the CL points) of the tool spaces during processing. With the rapid development of numerical control technology, its level and popularization has become an important symbol which is a measure of a country's comprehensive national strength and industrial modernization level. This design is to design mechanical machining and numerical control processing programming for the lid of Speed change box, The first is to design a machining, select cuttersand the rotational speed of main axis and the actual cutting speed, and so on, and then base on the chose cutters, the rotational speed of main axis and the actual cutting speed, and so on, install in the corresponding parameters ,simulate processing with Cimatron software, Its specific contents are as follows : 1. I further understood the concrete shape of the components by drawing engineering plat and three dimensional modeling chart of this components. 2. The machining of part has been designed according to the quality requirement and technical design component and a reasonable benchmark positioning also has been chosen , and then complete the processes of the relevant cards. 3. I designed a jig chart of a working procedure, and drew up the main detail drawing and the assembly drawing of the jig. 4. A numerical control simulation processing has been done in Cimatron software.Finally processing the numerical control processing of the part and the . G code generated.
