What aspects of knowledge do you need to learn CNC well, I am a novice, please advise

Numerical control technology, that is, the process of using computer programs to control the machine, and processing mechanical parts according to the program prepared by the staff in advance. Development trend: The application of CNC technology has not only brought revolutionary changes to the traditional manufacturing industry, making the manufacturing industry a symbol of industrialization, but also with the continuous development of CNC technology and the expansion of application fields, he plays an increasingly important role in the development of some important industries (IT, automobile, light industry, medical care, etc.) of the national economy and people's livelihood, because the digitization of equipment required by these industries has been the general trend of modern development.

From the perspective of the development trend of CNC technology and its equipment in the world, its main research hotspots are as follows: 1. Efficiency and quality are the main body of advanced manufacturing technology. High-speed, high-precision machining technology can greatly improve efficiency, improve product quality and ...

First of all, you need to know what kind of system you are making the machine tool. Start with manual programming, such as what kind of program and tool combination can be used to make the machining more efficient. In addition, you will have to learn how to sharpen the knife and find the center of the machine.

Then you can learn some CNC auxiliary software, such as UG, mastercam, etc.

I wish you early independence.

It takes so much, don't freak people out. This seems to be the content of a four-year undergraduate study in mechanical engineering. If you just want to learn CNC technology, you don't need it at all. You can study hard for 2 years in a technical school, and the key is practical experience.

Basic courses in science and engineering: advanced mathematics, physics, electronics, electrical engineering, etc.

Computer automatic control courses: computer principles, programming languages, automatic control, etc.

Basic Mechanical Courses: Mechanical Drawing, Mechanical Principles and Design, Fluid Mechanics, Hydraulic Principles, Material Mechanics, Tolerance and Fit, Metal Materials and Heat Treatment, Mechanical Manufacturing and Processing Technology, etc.

Learn more about modern machining technology and machine tools outside of class.

And, of course, English.

If you only pay attention to starting as soon as possible and familiarize yourself with the operation, there are several ways:

1.Read the user manual of the relevant machine tool, understand, and ask if you don't understand.

2.Ask for advice from the skilled masters around you.

3.Machining technology Tolerance and fit Heat treatment of metal materials is a must-see, pick one of the content related to the machine tool you operate to learn to understand.

4.Find out if there's one in the bookstore"CNC machine tool training"Take a look at textbooks and books like that.

Just look at the machine operating instructions and programming instructions.

If you just learn how to operate, it is enough to read the manual; This is not difficult.

Of course, how to process a part, you must also know how to read the engineering drawing, and be familiar with the processing technology; I think the main difficulty is in this aspect.

If the foundation of machining is already available, then the first step is to learn the principle of numerical control, then the coordinate system of the numerical control machine, and then learn the basic instructions of numerical control programming, write simple numerical control programs, and learn the operation of numerical control machine tools.

Related books include "CNC Machining Technology" and "CNC Machine Tool Programming and Operation". "CNC Machining Technology" This is a comprehensive course of CNC major, which tells you how to process a good part of the course, which may cover part of the previous books, if you have a more systematic CNC machining technology book, you can omit some of the previous books according to the content of the book. In addition, some mathematical foundations are required, such as geometry, trigonometric functions, and plane analytic geometry.

CNC, as the name suggests, is a technology that uses computer numerical control, so the English abbreviation CNC (numbericalcontrol technology), the most critical is the control part, through the PLC ladder diagram to identify each unit control and run through electrical control? The main control is how to cut and what to cut? Generally metal-based.

To learn CNC technology, we must focus on learning CNC machine tools and CNC technology and programming. Especially in the practical process, we should be more serious, do more, think more, and improve quickly. Because this major is a highly practical major.

In addition, the basic courses related to it should also be learned as much as possible, such as: mechanical principles, mechanical design, mechanical drawing, hydraulic transmission, electromechanical transmission, machine tool electrical control, testing technology, single-chip microcomputer technology, etc.

CNC technology and CNC equipment are an important foundation for the modernization of the manufacturing industry. Whether or not this foundation is solid has a direct impact on a country's economic development and comprehensive national strength, and has a bearing on a country's strategic position. So is it hard to learn CNC majors?

CNC major is still relatively difficult to learn, learning CNC is mainly divided into the following steps:

Stage 1: The learning of basic knowledge, including the basic knowledge of CNC machining principles, CNC programs, CNC machining technology, etc.

Stage 2: The learning of CNC programming technology, on the basis of a preliminary understanding of manual programming, focuses on the lack of interactive graphic programming technology based on CAD CAM software.

Stage 3: CNC programming and machining exercises, including a certain number of CNC programming exercises and actual machining exercises for actual products.

CNC is generally called program control, which controls the feed of each axis and the movement of the tool by the program. If you want to learn CNC well, you must at least learn 3D drawing, and you must also know how to use software such as PROE and UG.

If it is only a CNC lathe (two-axis) or a wire cutting machine, it is generally just a matter of electronic drawing, such as CAXA or CAD. 2D programming is as simple as looking at the manual.

CNC is a mechanical course, we usually say that the ordinary lathes and milling machines used in machining, and CNC is different from the original reason for adding a set of CNC equipment.

CNC equipment is basically composed of CNC system and servo system, which is a device that controls machine tools with electric pulse signals.

CNC technology is the basis for the manufacturing industry to achieve automated, flexible and integrated production; It is an indispensable technical means to improve product quality and labor productivity; CNC technology is an important strategic material for national defense modernization; It is an important basic industry related to the national strategic position and reflecting the level of the country's comprehensive national strength. After joining the WTO, China is gradually becoming the "world's manufacturing center". In order to enhance competitiveness, manufacturing companies have begun to widely use advanced CNC technology.

According to statistics, there is currently a shortage of about 600,000 CNC machine tool operators in China. The shortage of CNC talents has attracted great attention from the leadership, the Ministry of Education, the Ministry of Labor and Social Security and other departments. "It is difficult to hire CNC technicians with a monthly salary of 6,000 yuan" and "mold technicians cannot be recruited with an annual salary of 160,000 yuan" have become hot issues in the whole society.

The Ministry of Education, the Ministry of Labor and Social Security, the Commission of Science, Technology and Industry for National Defense, the Ministry of Information Industry, the Ministry of Communications, and the Ministry of Health decided to implement the "Vocational College Manufacturing Skilled Talent Training Project", and strive to achieve the goal of cultivating more than 300,000 skilled talents in the manufacturing industry in five years, so as to alleviate the shortage of skilled talents in China's labor market.

Just do the operation, then you only need to know how to compensate, start, pause, and modify simple parameters on the CNC equipment panel!

CNC to do, then you need to know how to understand the drawings, process arrangement, understand the workpiece material, understand the tool material, learn CNC programming, parameter modification, interpolation calculation, understand the mechanical principle, understand the safety operation specifications, if the CNC equipment has an accessory fixture or the fourth spindle, you need to know a little pneumatic clamping or hydraulic clamping, and a little, familiar with their own processing of product parts.

Of course, what is said above is general, the so-called old, learn old, CNC fully understands, there is a lot to learn above, sometimes a program will be programmed, but the master will cycle programming, this gap is also very big!

1. CNC technology major mainly learns: mechanical drawing, mechanical design basics, CNC machining technology, CNC machining programming and operation, CNC principles and systems, CNC machine tool use and maintenance, CNC machine tool electrical control, etc.

2. Numerical control technology is a technology that uses digital information to control mechanical movement and working process. This major cultivates students to engage in CNC machining, mechanical product design and manufacturing, production technology management, etc., and is a characteristic major with practical skills.

3. CNC technology requires the learning chain and students to be engaged in product manufacturing and development work at the production site, or to engage in process and management work in the technical department. It mainly cultivates students' theoretical knowledge and professional knowledge in the operation, repair and maintenance of CNC programming, machining and CNC lathes, CNC milling machines, CNC machining centers and other CNC equipment.
