Abstract
Design: Design "ram" parts of the machining process planning and process equipment, spare parts and to map out plans ram, ram rough map, fixture assembly, the fixture parts map. Complete machining process integrated card, a card processing machine. The preparation of curriculum design specification.
     Design significance: the design of this course is an important aspect of the practice of teaching. Completed internship in the production, completion of machinery manufacturing and technological foundation and other professional courses conducted. The adoption of the curriculum design, will learn theory and practice of combining production, tempered his analysis, problem-solving abilities, in the process I am an independent analysis and solution of the manufacture of mechanical parts of the problem, design a machine for this fixture A typical technology equipment, improved structural design capability for future graduates to design their own future and will be engaged in the work of an adaptation training, thus laying a good foundation.
Key words: ram; curriculum design, technology point of order, technology and equipment;
