Abstract
The flange parts processing technology and fixture design is the design of process design, including the parts processing process design and the three part special fixture. In the process of design should first of all parts to analyze, understand parts of the process and then design a blank structure, and choose the good parts of the machining datum, designs the process routes of the parts; then the parts each step process dimension calculation, the key is to determine the process equipment and cutting the amount of each working procedure design; then a special fixture, fixture for the various components of a design, such as the connecting part positioning device, clamping element, a guide element, clamp and the machine tool and other components; the positioning error caused calculate fixture when positioning, analysis of the rationality and deficiency of fixture structure, pay attention to improving and will design in. Keywords: process, process, cutting, clamping, positioning,
