By the use of basic theoretical knowledge, the correct solution in the processing of the workpiece positioning and clamping problem, a reasonable choice of programmes, carry out the necessary calculations, based on that design intended to meet the requirements of low-cost fixture. 2. To collect relevant information, have the right fixture design ideas, ways and means to learn the correct use of the manuals and other technical information. 3. Analysis of the structure of issues, enhance structural design capacity. 4. Learn more about machine tools, cutting tools and measuring tools, such as the tooling knowledge. 辽宁工程技术大学课程设计 IV 目录 1 拔叉的工艺分析及生产类型的确定............................................ 1 拔叉的用
