In process design should first of all parts for analysis, to understand part of the process to design blank structure, and choose the good parts machining datum, design the process routes of the parts; then the parts of each step in the process to the size calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, the fixture for the ponents of the design, such as the connecting part positioning devices, clamping element, a guide element, fixture and machine tools and ponents; positioning error calculated by the analysis of fixture, jig structure the rationality and the deficiency, pay attention to improving and will design. Keywords: process, cutting dosage, clamping, positioning 优秀机械毕业设计欢迎下载, 学****交流加 QQ 197216396 专业机械设计解君之忧 IV 目录摘要........................................................................................................................................
