是呀门课（Yes, its a class） We had four Metalworking Practices at school and finally finished. During the period, we came into contact with the car, pliers, milling, grinding, welding, casting, forging, CNC machining and other workpieces. Almost every day we learn a new skill under the guidance of a teacher. Therefore, each of us has its own pieces of work done, although the quality is not satisfactory, but the sweat of which we are gratified, but also a sense of achievement. Overall, this internship is an interesting and important experience that will affect future learning and work. Metalworking practice is a practical technical basic course, which is the basic process method and technology for engineering students to learn mechanical manufacturing, and an important required course for basic training. Metalworking practice not only allows us to obtain the basic knowledge of machinery manufacturing, to understand the general operation of machinery manufacturing, but also can improve their skills and ability, and strengthen the theory and practice of the training, improve the ability of engineering practice that we train our engineering quality. Metalworking practice is a good opportunity for us to study and exercise. This is short and full of practice I learned a lot, this internship training to our observation ability, ability, broaden our horizons, so we usually learn the theoretical knowledge and practice of effective combination. During the internship, we were learning the casting, Turner, Xigong, fitter, CNC wire cutting, and other mechanical equipment structure, working principle, basic operation and basic functions. In metalworking practice, safety is the first, and this is the first advice given by each teacher. So, in practice the first day the teacher gave me the door on the safety knowledge education, enumerates some unsafe operation examples, the safety problem of various types of work should pay attention to, such as not in operation when playing, long hair
