Fork fixture design process planning and milling machining parts that include process design, process design, and special fixture design of three parts. In the process of designing the parts tobe 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 ofa key is to determine the technical equipment and cutting the amount of each process ; then dedicated fixture design , select the design of the ponents of the fixture , such as positioning elements , clamping elements , guiding element , clamp connections and machine parts and ponents ; positioning error generated when calculating the fixture , analytical rationality and inadequacies fixture structure and attention to improving the design in the future . Keywords : fork , processes, cutting the amount of clamping 目录 IV 目录摘要.....................................................................................................................
