成。教师的指导作用是指明设计思路，启发学生独立思考，解答疑难问题，按设计进度进行阶段审查，学生必须发挥主观能动性，积极思考问题，而不应被动地依赖教师查资料、给数据、定方案。
(3) 设计中要正确处理参考已有资料与创新的关系。任何设计都不能凭空想象出来，利用已有资料可以避免许多重复工作，加快设计进程，同时也是提高设计质量的保证。另外任何新的设计任务又总有其特定的设计要求和具体工作条件，因而不能盲目地抄袭资料，必须具体分析，创造性地设计。
(4) 学生应按设计进程要求保质保量的完成设计任务。
液压与气动课程设计原始资料
课程设计内容（含技术指标）
设计中等复杂程度的机床液压传动系统，确定液压传动方案，选择有关液压元件，设计液压缸的结构，编写技术文件并绘制有关图纸。
1、 设计一台专用卧式铣床的液压系统，要求液压系统完成“快进—工进—快退—停止”的工作循环。已知：，铣刀直径为120mm，转速为350r/min，工作台、工件和夹具的总重量为5500N，工作台快进行程为250mm，工进行程为150mm，快进、，工进速度为60—1000mm/min，加、，工作台采用平导轨，，。
2、 设计一台专用卧式钻床的液压系统，要求液压系统完成“快进—工进—快退—停止
