1.使学生具有制定工艺规程的初步能力。能综合运用
械制造技术基础和其他课程的基本理论和方法，正确的制定一个零件的机械加工工艺规程。
2.具有设计专用夹具的初步能力，提高结构设计能力。
3.结合工艺设计内容，能够熟练的应用工艺计算方法
正确的进行公义计算。
4.进一步提高查阅资料，熟练地使用设计手册、参考资
料等方面的能力。
5.通过设计的全过程，使学生学会进行工艺设计的程序
和方法，培养独立思考和独立工作的能力。Abstract
The curriculum design are the main contents of fixture design, aimed at the adoption of the curriculum design, will learn theory and practice of combining production, resolved the issue of capacity issues and the initial training, and to do a good job after graduating from design and embarked on work Posts to conduct a comprehensive training. Through the design of the course, students should receive training in the following areas:
1. So that students have developed a point of order of the initial capacity. Can make comprehensive use of
Firearms manufacturing technology and other courses based on the basic theories and methods, the right to develop a parts order processing machinery.
2. Fixture with the preliminary design for capacity and improve structural design capacity.
3. Combination of design, the application process can be skilled calculation method
The right to justice calculation.
4. Further improve access to information, skilled use of Design Manual, the reference to funding
Materials such as the ability.
5. Through the entire process of design, process design students to learn the procedures
And methods, and foster independent thinking and the ability to work independently.
