This course is designed to plete the production internships, pletion of machinery manufacturing and techno logical foundatio n and other profess ional courses conducted. Students through the curriculum des ign, will learn theory and practice of b ining production, resolved the issue of capacity issues and the initial training, and also do a good job after graduatio n for the des ign and embarked on a prehens ive training for jobs. Through the courses, students in the following areas should be tempered: 1. So that students have developed a point of order of the initial capacity. Can make prehens ive use of machinery manufacturing techno logy and other courses based on the bas ic 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 des ign, the application process can be skilled method of calculating the correct conduct of calculatio n, such as technic al parameters, cutting force, cutting power, cutting speed, positioning error, the clamping force, and so on. 4. Further improve access to informatio n, skilled use of Des ign Manual, reference materials, such as the ability. 5. Through the entire process of design, process design so that students will carry out the procedures and methods, and foster independent thinking and the ability to work independently.
