At school, I study hard for professional knowledge. My major is CNC machine tools. If I learn this major well, it will be a good career in the future. If I don't learn it well, I will be useless. In order to study better, I specially participated in the internship organized by the school. Now I will make a summary of this internship.

This CNC intermediate training is mainly about pa system, including lathes and milling machines. I mainly practiced NC programming before summer vacation, but I prefer machine tool operation this semester. Through computer programming simulation and lathe operation, as well as processing parts. Have a certain grasp of the learning of intermediate CNC.

Personally, I am interested in a preliminary understanding of programming. From a little knowledge at the beginning to being familiar with using every command and understanding its meaning now, my constant exploration every day is closely related to the patient teaching of the teacher. Mainly summarize the following points:

First, the understanding and application of numerical control programming and simulation

It is an honor to have such a good teacher to teach us NC programming. In fact, the most important thing in learning is to practice more on your own, but at the key time, with the guidance of teachers, you make rapid progress. Especially when I first came into contact with programming and processing, I made great progress under the guidance of teachers. I remember that on August 9th, the teacher began to talk about the programming process, especially the frequently used codes, and then the understanding and calculation of the main points. Simulation of machining simulated parts. Through the study of these knowledge points, I gradually understand some basic essentials of NC programming. Tool alignment on the machine tool is a difficult problem I encountered before, because I am not used to using commands and have a poor understanding of basic feelings. However, through repeated practice, I am now familiar with the simulation system. Now I can read the map and know the cutting route. And the integral involved can be converted.

Second, the actual handling and mastery of learning methods.

For the operation of machine tools, I always feel that I haven't practiced enough, especially the processing of parts, and I don't have a good grasp of the actual knife. Although I can process parts now, and the dimensions are properly grasped, the time control is still not good enough. This is mainly because I am not skilled in operation.

Now I have been able to finish the lathe, tool alignment and machining within the specified time, and the size can meet the requirements, but I think it is because I spend more time on the lathe. On the other hand, the milling machine is not skilled enough. Although it knows how to deal with it, the size control and time control are not good enough. However, through constant practice and practice, I got a good promotion, and I was able to process parts and solve small problems on machine tools. Especially in the last period, I was able to process parts. And the size is well grasped, which meets the requirements on the drawings.

Third, the study and understanding of theoretical knowledge.

I carefully studied the information sent by my teacher. Of course, it is necessary to remember that there is still a certain gap in every knowledge point, but I am confident to learn the theoretical knowledge well. I think the most important thing is to understand every knowledge point, not to memorize it, because a lot of theoretical knowledge will be used in practical operation and must be mastered. Only by fully understanding the theoretical knowledge can we better complete the actual operation. For example, buttons on machine tools, tool paths, tool repair, etc. Both involve a lot of theoretical knowledge. Only by thoroughly understanding the theoretical knowledge can we seriously abide by the rules in the processing process and complete the processing of parts more safely.

Fourth, harvest

In the learning process of NC programming and machining, I don't think about what I have learned, but about learning methods. I am honored to be helped by my teacher. They can communicate with me better when I am confused and tangled in my study. When they talked to me about the usefulness of studying this course and the direction of my future work, I felt it was worthwhile. After entering the university, it is no longer an exam-oriented education in high school. Everyone should find a suitable learning method. Only by mastering good learning methods can we learn our own courses well. Moreover, during the period of studying CNC, I have been groping constantly and feel that I have gained a lot.

Verb (abbreviation of verb) has shortcomings and personal expectations.

Although I have mastered the intermediate knowledge of numerical control now, I can process parts. Mastered the relevant theoretical knowledge and operational skills. But when it comes to some special parts, it takes time to think about the processing route. Without programming, you will forget your original knowledge if you get off the plane for a long time. So I will cherish every opportunity to operate in the future. Seize the opportunity and make better use of what you have learned. Compared with the ocean of NC knowledge, I just learned the tip of the iceberg, and I know I still have a lot to learn. I will study hard the knowledge of numerical control on the original basis. Can be engaged in mechanical processing industry, can be owned by schoolmates, can be harvested by schoolmates. I hope to make better use of relevant knowledge to serve this society. At the same time, I hope I can learn more professional knowledge through my own efforts and teachers' teaching.

Chapter 2: Summary of lathe practice report.

Learning electronic numerical control in class is mostly theoretical knowledge, so I cherish this internship opportunity, listen carefully to the teacher's explanation and introduction, observe the structure and parts of each machine, learn its practical methods, and combine theoretical knowledge in order to understand it more thoroughly.

The internship visited a CNC machine tool. First of all, our classmates visited in order, and then the teacher introduced me to the requirements that should be paid attention to when visiting. Don't touch the machine or press the switch. Then, under the guidance of the teacher, I learned the programming of CNC lathe through computer operation. Because it is a computer operation, we must first learn the language and instructions that the computer can recognize, so that we can correctly input instructions to control the computer and get the products we need. After writing the program, we can watch the simulation, know in advance whether the program meets the requirements and standards, and finally contact the machine tool to input the programmed program into the CNC machine tool. Everything is automatic, and the processing speed of parts is fast, which meets our requirements, so CNC machine tools are very contemporary. It is said that the development and upgrading of CNC machine tools are almost synchronous with the development of computers.

Through this internship, we learned about the production mode and technological process of modern machinery manufacturing industry. Familiar with the main molding methods and processing methods of engineering materials, the working principle and typical structure of the main equipment used, the use of fixtures and measuring tools and the safe operation technology. Understand the knowledge of mechanical manufacturing process and the application of new technology, new technology and new equipment in mechanical manufacturing. Have preliminary independent operation skills in the main molding and processing methods of engineering materials. In the process of understanding, being familiar with and mastering certain engineering basic knowledge and operation skills, we have cultivated, improved and strengthened our engineering practice ability, innovation consciousness and innovation ability. This internship made us understand that we should be careful and not careless. At the same time, it also cultivated our strong and unyielding nature, and never gave up perseverance until the last second! We have cultivated and exercised our own views on labor, quality and economy, strengthened our awareness of observing labor discipline, safety technical regulations and caring for state property, and improved our overall comprehensive quality. During the whole practice, the teacher was very strict with our discipline, formulated the rules for students' practice, and at the same time strengthened the requirements of cleaning the machine tool site and observing the safety operation rules of various types of work, which played a very good role in promoting the cultivation of students' comprehensive engineering quality.

For the first time in my life, I have a feeling of "applying what I have learned", and I feel a sense of accomplishment in my heart, and I really realize that truth must be tested by practice, rather than trying it myself. There are many things that are not in books and can only be realized in practice. Talking on paper will only lead people into misunderstanding, and practice is the eternal teacher. It not only brings us experience, but also lets us know what work spirit and serious style are. In my future study career, I will learn from real people and become an excellent professional in the future. This internship taught me what it means to "talk on paper, concentrate on practice and gain true knowledge".
