XX Abstract Parts and fittings drilling fixture design process includes parts machining process design, process design, and special fixture design three parts. In the process of designing the parts to be the first analysis to understand the parts of the process re-design the structure of the blank, and select the machining datum good parts, the design process route parts; then the part of each step of the process to calculate the size of a key is to determine the technical equipment and cutting the amount of each process; then dedicated fixture design, select the design of the various components of the fixture, such as positioning elements, clamping elements, guiding element, clamp connections and machine parts and other components; positioning error generated when calculating the fixture, analytical rationality and inadequacies fixture structure and attention to improving the design in the future. Keywords: technology, processes, cutting the amount of clamping, positioning error 2 Abstract2 1 4 2 5 2.1 5 2.2 6 3 6 3.1 6 3.2 6
