Metalworking NC Teaching Methods
On behalf of Wing et al: metalworking 159 NC teaching methods for students with high interest in learning and practice effect for the future of practice teaching provides a teaching ideas. Fourth, the combination of theory and practice, practice teaching is an important method of CNC metalworking practice teaching should be mainly practical ability of students in the importance of improving the same time should pay attention to comprehensive abilities of students, to enable students to have the initiative in practice, so In practice they can think independently, to analyze and solve problems and improve their ability. In addition, in practical terms the students to further strengthen the basic training required to master the basic skills required. For example, in NC machining, product design, computer graphics, modify the programming, processing,[link widoczny dla zalogowanych], manufacturing and other sectors to link up the students the entire process of production has an intuitive understanding. Because less time to practice NC and contents, teaching takes a long time, the students hands-on time is relatively less. In addition the value of expensive CNC equipment, a small number of relatively tight operating time. 1O the students are generally divided into a group of people together to complete a processing operation. However, the quality of students is different, and some thinking ability, and some strong spatial imagination, and some hands-on ability, which requires teachers to look carefully, in time, individual instruction. According to general teaching students their first step is to read, then the structure of teachers on the principles of machine tools,[link widoczny dla zalogowanych], machine tool operation demonstration, let the students themselves familiar with the operation of machine tools, and then to the students about programming and programming to the students themselves, and finally to the machine practical operation of machining the workpiece]. But according to this teaching method, to spend so much time given to CNC metalworking practice for the teaching time to complete these tasks is completely inadequate. Therefore, teachers can be based on the actual adjustment of the situation, along with updated equipment and the different types of students, teachers should be based on the circumstances appropriate adjustments. For example, in programming to the students about how to make a limited time students is not mechanical professional programming, to accept the content of teaching is a very important and challenging research topic. I just started speaking program, always talk about the theory, and then give the students an example. Is a reflection of the students understood,[link widoczny dla zalogowanych], but the theory can not remember,[link widoczny dla zalogowanych], it will not apply. Students had no time to go on reading, there is reluctant to read. This is not a very good teaching results. Later, the authors summarize the experience of teaching, and telling example of theoretical side, students are very easy to understand, easy to remember to teach the content, teaching is very good. Theory and practice in explaining the fully integrated, rather than theory and examples into two separate parts. This requires a deep understanding of the teacher and master the material and its contents and characteristics of law students to learn knowledge. I metalworking practice teaching in NC, to closely combine theory with practice, in practice, to explore a way of teaching has its own characteristics. NC on the metalworking practice teaching: (I) requires teachers to establish a correct attitude towards the teaching, practice teaching to grasp the correct numerical position. Instructor during the teaching arrangements, the lively atmosphere from classroom teaching, the students receptive to proceed to achieve better teaching results. Note that in the lecture board layout,[link widoczny dla zalogowanych], the use of teaching facilities, the production of courseware, students not only mastered the knowledge and cultivate a sentiment; (2) to formulate a curriculum to meet the requirements of metalworking content. In the process of guiding students to grasp learning situation, a reasonable adjustment to modify training content in a timely manner; (3) teachers should have the units have some knowledge of CNC equipment, seek common ground, in practice, lessons learned, make full use of and create the conditions mobilize the enthusiasm of the students in order to achieve better teaching results. In short, in order to constantly improve the CNC Turning practice teaching methods, to achieve a best practice effect, and can be with students, teachers need to have a high sense of responsibility, and in guiding the process to detect and resolve problems, and continuously improve teaching methods in order to enable students to school in a relaxed atmosphere to knowledge, to achieve better learning outcomes
