车工实习(国外英文资料) The practice is to train the students to use the skills of the lathe and the operation lathe, and to meet the requirement of the technical grade standard. There are a lot of materials, knives and various kinds of measuring tools that need to be used during the internship. The cost of the material and the loss of the tool are considerable, and many expensive gauges are only used in the processing of specific artifacts. In response to this situation, it is necessary to explore some effective ways to reduce the cost of internships in schools. In this paper, the author summarized the experience of the practice teaching, and summarized the three aspects of the section.
