Application Research of CNC Machining Simulation System Software in Numerical Control Teaching and Identification

The development of the global knowledge economy has made mechanical engineering a comprehensive technical application discipline spanning multiple disciplines such as mechanics, electronics, computers, information, control, management, and economics. CNC machining application technology has emerged as the times require. This is a machine in the traditional sense. Processing professional education has put forward new and higher requirements. Zhuzhou Institute of Technology seizes the opportunity, is keen on reform, actively explores a new mode of training professional talents for CNC machining, and strives to cultivate high-level, complex, open and skill-based CNC machining application technical talents at the intermediate and advanced levels. Economic construction transports a large number of applied skills and talents.

Since 2000, our school has been training students of CNC machining, taking the lead in innovating the teaching content of professional subjects, actively reforming the teaching mode of CNC machining technology and applying the research of CNC machining simulation system in NC teaching and identification, and achieved good results. The teaching and appraisal effect has been welcomed by students, parents and the society, making the NC major become one of the fist professions of our school. The students majoring in CNC account for one-third of the total number of students in our school to meet the talents of CNC machining. The urgent needs of the cultured society.

First, the question is raised

With the development of science and technology, CNC machining technology is being widely used. CNC talents have become urgently needed talents in the labor market. How to train NC skill-based talents that meet market needs and master CNC machine tool programming knowledge and operation technology as soon as possible has become a problem that CNC teaching workers must study. As a professional teacher of CNC programming and operation, I deeply feel that how to combine NC programming teaching with CNC machine tool operation practice is worthy of our careful discussion and research.

Since CNC machine tools are a new type of process equipment, the training of CNC technicians and the teaching of CNC machine tools are still in their infancy. How to use the CNC machining simulation system for teaching and identification is in the exploration stage, so it is necessary to The NC teaching mode, teaching methods and teaching methods are improved, and the working methods of professional skills appraisal of NC majors are innovated, and a complete set of new NC teaching and appraisal system is established.

CNC machine tools are high-tech products, and the variety is high. The price of a CNC lathe or CNC milling machine is generally 200,000,000, and the number of a CNC machining center is as low as several hundred thousand and several million. If the operation training of CNC machine tools is completely dependent on CNC machine tools for practical training, the investment is high and the cost is high. Even the powerful training schools and enterprises are neither necessary nor able to bear such consumption and input. Therefore, it is inevitable to explore a new teaching mode of NC machining technology to achieve less investment, quicker effect, and adaptable students. The popular teaching mode is inevitable. This teaching mode should be different from the traditional mechanical processing mode. It is different from the general electromechanical profession. Teaching CNC machining simulation system is an important way to solve this problem. It can not only solve the problem that the students are not familiar with the operation and control panel of the CNC system during the internship, but also greatly improve the students' interest in learning. It can also improve the students' programming ability and adaptability to different CNC machine tools of different CNC systems. It is effective. A good attempt to conduct pre-school teaching of numerical control practice is also an effective means of conducting professional skills assessment of CNC machine tools.

Second, the determination of the teaching mode of CNC machining technology

The professional training of the application of CNC machining technology in vocational and technical education is to enable students to acquire the professional skills of numerical control technology application, and to obtain the protection needed for the survival and development of this professional skill, that is, to learn an advanced life for the society. Skills. To this end, we have actively explored and researched the teaching mode of CNC machining application technology, aiming to establish a set of reasonable training system for training and appraisal of CNC machine tools. Our guiding ideology and goals are:

1. Comprehensively reform the teaching mode of CNC machining technology, realize two transformations, that is, the change from theoretical teaching to theoretical teaching and skill training, and combine the pure operation and pure consumption of skill training with the numerical simulation system to verify the programming effect. The transformation of training;
