How about NC programming?

Question 1: How about NC programming? The numerical control industry is not so good, not to mention the high salary and poor working environment. It's just a programming language. It's simple. You'd better learn manual programming and then UG. Of course, these are only superficial, mainly work experience. Like processing technology and cutting route, it takes time to accumulate. You have been working for more than ten years, which is about seven or eight thousand. You might as well do something else.

Question 2: How to do CNC programming 20 points teaches you how to become a master of CNC machine programming, and it is recommended that beginners read it carefully. If you want to become a master of numerical control (metal cutting), it will take at least six years from graduation to entering the factory. He should not only have the theoretical level of an engineer, but also have the practical experience and ability of a senior technician. Step 1: You must be an excellent craftsman. CNC machine tools integrate drilling, milling, boring, reaming and tapping. The technical literacy of technicians is very demanding. Numerical control program is the process of reflecting machining technology with computer language. Technology is the foundation of programming. If you don't know the process, you can never say that you can program. In fact, we choose the major of mechanical cutting, which means the hardships and frustrations in the early stage of employment. The basic knowledge learned in the university is too little to meet the needs of the factory. Engineers in mechanical processing are experienced engineers to some extent. So I have to spend a lot of time with workers, such as dry lathes, milling machines, grinders, machining centers and so on. Subsequently, the process, material consumption and quota are compiled in the office. You must be familiar with the performance of various machine tools and the technical level of workshop masters. In this way, after 2-3 years of practice, you can basically become a qualified craftsman. From my personal experience, I suggest that young college students who have just joined the work must learn from the workers with an open mind. Once they can teach you decades of experience, you can avoid taking many detours. Because these experiences can't be learned in books, the choice of technology is to comprehensively consider the choice of equipment ability and personnel technical ability. Without the support and trust of employees, it is impossible to become an excellent craftsman. Through such a long period of study and accumulation, you should meet the following technical standards and requirements: 1, be familiar with the structure and technological characteristics of drilling, milling, boring, grinding and planing machine tools, and 2, be familiar with the properties of processed materials. 3, solid basic knowledge of tool theory, master the conventional cutting parameters of tools, etc. 4. Be familiar with the process specifications and guidelines of this enterprise, the general requirements that various processes can meet, and the process route of conventional parts. Reasonable material consumption and man-hour quota. 5. Collect a certain number of tools, machine tools and mechanical standards. Especially familiar with the tool system used in CNC machine tools. 6, familiar with the choice and maintenance of coolant. 7. Have a common sense understanding of related work. Such as casting, electro-machining, heat treatment, etc. 8. Have a good fixture foundation. 9. Understand the assembly requirements and use requirements of the processed parts. 10, which has a good measurement technology foundation. Step 2: Proficient in numerical control programming and application of computer software. I think this is relatively easy. There are dozens of programming instructions, and all kinds of systems are similar. It usually takes 1-2 months to get familiar with it. Automatic programming software is a little more complicated and needs to learn modeling. But it is not difficult for people with good cad foundation. In addition, if it is manual programming, analytic geometry foundation is also better! Scholars are best suited to study this knowledge. In practice, the standard of a good program is: 1, which is easy to understand and organized, and can be understood by all operators. 2. The fewer instructions in the program segment, the better, aiming at simplicity, practicality and reliability. From the programming point of view, I think the instructions are G00 and G0 1, and the others are auxiliary instructions, which are set for the convenience of programming. 3. Easy adjustment. When the machining accuracy of parts needs to be fine-tuned, it is best not to change the program. For example, if the tool is worn, to adjust it, just change the length and radius in the tool offset table. 4. Convenient operation. Programming should be compiled according to the operating characteristics of machine tools, which is beneficial to observation, inspection, measurement and safety. For example, the same kind of parts and the same processing content are processed separately in vertical machining centers and horizontal machining centers, and the procedures are definitely different. In machining, the simplest method is the best method. Anyone with practical experience will agree with this sentence! Step 3: Skillfully operate CNC machine tools. It takes 1-2 years of study, and the operation is very tactile. Novices, especially college students, know what to do in their hearts, but their hands just don't listen. In this process, we should learn: system operation mode, fixture installation, part reference alignment, tool alignment, zero offset setting, tool length compensation and radius compensation, tool and handle disassembly, tool sharpening, part measurement (skilled use of vernier caliper, micrometer, inner diameter lever table) and so on. Horizontal machining center and large gantry (moving beam and top beam) machining center can best reflect the operation level. The operation needs to be understood! Sometimes there is an artistic conception that "the mind is carefree, and it is difficult for a beauty to talk to you"! Just calm down and practice in the CNC workshop! Generally speaking, from processing the first part to processing >>

Question 3: What is the prospect of C programming? At present, there are many people engaged in numerical control programming, which have basically met the market demand.

Now machining is in the decline stage.

Preliminary estimates should be good. After all, this is a basic industry.

Learn programming first, and learn operation first.

Question 4: How to compare NC programming S F is generally as follows: F function F function instruction is used to control cutting feed. In the program, there are two ways to use it. (1) The number after the programming format G95 F~ F indicates the feed rate per spindle revolution in mm/r. Example: G95 F0.2 indicates the feed rate of 0.2 mm/r. (2) The programming format G94 F~ F indicates the feed rate per minute in mm/min. For example, G94 F 100 means that the feed speed is 100 mm/min. 2.S function S function instruction is used to control the spindle speed. The number after the programming format s ~ s indicates the spindle speed, and the unit is r/min. On the machine tool with constant linear speed function, the S function instruction also has the following functions. (1) The number after the maximum speed limit programming format G50S ~ S indicates the maximum speed: r/min. For example, G50 S3000 means that the maximum speed is limited to 3000 rpm. (2) The number after the constant line speed control programming format G96S ~ S represents the constant line speed: m/min. Example: G96 S 150 means that the linear speed of the cutting point is controlled at 150 m/min. (3) The number behind the programming format G97s ~ s for canceling the constant line speed indicates the spindle speed after canceling the constant line speed control. If s is not specified, the final value of G96 will be retained. Example: G97 S3000 indicates that the spindle speed is 3000 r/min after the constant linear speed control is cancelled.

Remember to adopt

Question 5: How to find a job without numerical control programming experience? In 30 minutes, you can be a CNC operator first, don't do that kind of mass production, accumulate experience while doing it, and then you can jump ship to do CNC programming.

If you have an apprentice in CNC programming, you can apply.

Question 6: What is the salary of NC programming * The competitiveness data of this industry only represents the C programming situation, not the national data. The data shows that C programming has the highest salary in the "finance/investment/securities" industry, which is 6960 yuan; The highest salary in "Ningbo" area is 6700 yuan.

Question 7: How to learn NC programming? A lathe in 30 minutes will do. There's a chance. There's nothing wrong with it. CNC lathes mainly learn technology and parameters. That is experience. No matter how it changes, the process of a part is the same, whether it is ordinary or numerical control. I hope you can learn the basic clamping and process well first. Programming is nothing. The most important thing is the craft. You must know how to machine a part. So I hope you can seize this opportunity to study hard? You can do it. Learn from experience. I hope the above answers are helpful to you. I wish you success!

Question 8: What is numerical control? How to learn CNC technology well? Is programming difficult? Personally, NC programming is not difficult. It is conceivable that so many things have died.

If what you have learned in the factory has not been systematically taught, I suggest you put your mind right first. It's not difficult at all. Just logical thinking is better, online programming is no problem.

I met some advanced programs, such as macro programs (misled by my teacher, he said it was as difficult as it was). As a result, we are all afraid that it is not half as difficult as software programming, but something I hate very much.

The key is to practice more and you will be OK. If you have a computer, you can input your own small program into the computer and walk it again, so as to avoid some knife collision mistakes and increase your confidence. There are many such softwares. For example, Swarm CNC Aerospace suggests that the trial version of Swarm is enough! !

Besides, it's no use knowing how to program. The codes in various machines are also different, such as Siemens' and Frank's, which are also very different from Huazhong CNC, and even less than Madzak machine tools (man-machine dialogue programming).

You just need to learn slowly step by step, and you don't need to rush for success! ! If it is CNC milling, you can try to program automatically after you know it is manual, which can save a lot of time on some complex surfaces with large programs! ! !

Question 10: how to learn NC programming first of all, I want to emphasize that if you can NC program various languages, then you will have a great advantage in the competition of social talents.

At present, with the rapid growth of domestic manufacturing demand for CNC machining, there is a serious shortage of CNC programming talents, and CNC programming technology has become a hot demand in the job market.

A, learning numerical control programming technology needs to meet the following basic conditions:

(1) has basic learning qualifications, that is, students have certain learning ability and preparatory knowledge.

(2) Have the conditions to receive good training, including selecting good training institutions and training materials.

(3) Accumulate experience in practice.

Second, learning NC programming technology requires students to master certain preparatory knowledge and skills, including:

(1) Basic knowledge of geometry (high school or above is enough) and mechanical drawing.

(2) Basic English (above senior high school).

(3) Common knowledge of machining.

(4) Basic 3D modeling skills.

Three, the selection of training materials should be considered factors include:

The content of the textbook (1) should meet the requirements of practical programming application, with the interactive graphic programming technology based on CAD/CAM software widely used at present as the main content. Teaching practical techniques such as software operation and programming methods should also include some basic knowledge for readers to know more.

(2) The structure of teaching materials. The learning of NC programming technology is a process of continuous improvement in stages, so the content of teaching materials should be allocated reasonably according to different learning stages. At the same time, the content is systematically summarized and classified from the perspective of application, which is convenient for readers to understand and remember as a whole.

Four, the learning content and learning process of NC programming can basically be summarized into three stages:

Stage 1: Learn the basic knowledge, including the basic knowledge of NC machining principle, NC program and NC machining technology.

The second stage: the study of numerical control programming technology, focusing on the interactive graphic programming technology based on CAD/CAM software on the basis of a preliminary understanding of manual programming.

The third stage: NC programming and machining exercises, including a certain number of NC programming exercises and actual machining exercises of actual products.

Verb (abbreviation of verb) learning methods and skills

Like other knowledge and skills learning, mastering the correct learning method plays a very important role in improving the learning efficiency and quality of NC programming technology. Here are some suggestions:

(1) concentrate on fighting annihilation, concentrate on completing a learning goal in a short time, apply it in time, and avoid marathon learning.

(2) Reasonable classification of software functions can not only improve memory efficiency, but also help to grasp the application of software functions as a whole.

(3) From the beginning, it is often more important to cultivate standardized operating habits and rigorous and meticulous work style than simply learning technology.

(4) Record the problems, mistakes and learning points you usually encounter. This process of accumulation is a process of continuous improvement.

Sixth, how to learn CAM

The study of interactive graphic programming technology (that is, the key points of CAM programming that we often say) can be divided into three aspects:

1 is the core function of learning CAD/CAM software, because the application of CAD/CAM software also conforms to the so-called "20/80 principle", that is, 80% of applications only need to use 20% of its functions.

2. It is to cultivate standardized and standardized work habits. Standardize the parameter settings of commonly used machining processes to form a standard parameter template. These standard parameter templates should be directly used in NC programming of various products as far as possible to reduce the computational complexity and improve the reliability.

3, is to pay attention to the accumulation of processing experience, familiar with the characteristics of CNC machine tools, cutting tools, processing materials, in order to make the setting of process parameters more reasonable.

It should be pointed out that practical experience is an important part of NC programming technology, which can only be obtained through actual machining and cannot be replaced by any NC machining training textbook. Although this book fully emphasizes the combination with practice, it should be said that it is difficult to describe the changes of process factors in different processing environments in written form.

Finally, just like learning other technologies, we should "despise the enemy strategically and attach importance to the enemy tactically", and we should not only establish firm confidence in completing the learning objectives, but also treat every learning link in a down-to-earth manner.

Therefore, as long as you are interested in NC programming, I strongly support you to learn, and the future is boundless.
