[Abstract

]  With the rapid development of science and technology and increasingly fierce economic competition, mechanical products, updates faster and faster, CNC machining technology as the representative of the advanced productive forces, in the machinery-related industries play an important role in the field of mechanical manufacturing competition, and its essence is a numerical control technology competition. This class is designed to seat aircraft parts machining design, the components are single-sided processing of parts, according to parts fixture considerations, should be processed first appearance, and then processing cavity of the process, should follow the surface after the first hole, after the first coarse fine the processing sequence and processing time to pay attention in the programming and design of processing origin overlap. Second, the preparation of mounts Parts order processing process (including process card and CNC tool cards) and major processes of the tooling design. And use G code for the preparation of the parts of the CNC machining process, she then learn to use computer-aided process design-related knowledge, to add the necessary processing of images. 

Keywords: CNC machining, seat frame type components, CNC machining technology, computer-aided
