In fact, CNC is not as difficult as you think, to say that the connection between CNC and math, it is not very much with the function of the link, and it is linked to the most is the analytical geometry, as if a coordinate system to tell you that you want to find a point of space as well.
You said you can learn CNC, I think it is certainly possible, know that you have confidence in yourself, willing to learn, nothing can not be done, you say is not? To have confidence, CNC is not difficult.
What others have said, is the advanced programming of CNC "macro CNC", it is based on the function, there are independent variables, variables. And so on. In the field of CNC, when you have a certain level, naturally it is not difficult.
And you say CNC need any foundation? Oh, this point you do not worry, because you just learn CNC, the school will naturally tell you the basics, since you asked the question, then I will tell you
CNC? It is a automated, intelligent ***, the basis of which is mechanical drawing
CAD materials science, electronics and electrical engineering, etc.
Friends, learn it well, I and you race ah, huh
Question 2: learn CNC to learn what things? Learn CNC in secondary technical schools generally learn the main courses are: CNC machine tools, CNC programming, CNC machining process, computer graphics software CAXA or CAD, if it is a college or university to learn the basics of mechanical engineering and basic mechanical design, CNC machine tool failure and diagnosis. Mainstream computer programming software UG, PRO-E, EdgeCAM, MasterCAM and so on. If you just do CNC machining workers as long as you focus on learning the above part of the course can be done, if you do CNC machine tool maintenance also involves knowledge of mechanical transmission and electrical and electronic knowledge, if you do technicians or programmers to focus on learning CNC programming, CNC machining process, as well as drawing software and programming software. CNC in our country is mainly learned in China CNC programming The basic meaning is that through some specific code to control the machine operation work Learning is how to use these codes to give you a drawing you can read and understand can be based on the drawing to program the machine to work to make a variety of workpieces
Problem 3: learn CNC first learn what? CNC need to learn the public **** course are:
"Mechanical Literacy", "Mechanical Fundamentals", "Tolerance and Technical Measurement", "Metal Cutting Principles and Cutting Tools", "machine tool fixtures".
CNC courses: "CNC machining process", "CNC machine programming and operation".
If you study CNC machine tool maintenance or CNC machine tool design, you will need to take other courses.
The following is the main content of each book:
"Mechanical Drawing" This is the most basic course in mechanical manufacturing, introduces a variety of drawings of the expression, so that you can understand a variety of drawings,
belongs to the required courses. Many schools are using "mechanical drawing" instead of "mechanical literacy", mechanical drawing is drawing, higher than the requirements of mechanical literacy.
"Fundamentals of Mechanics" introduces the characteristics of various common mechanisms, applications.
"Tolerance and Technical Measurement" This is a course that teaches you to read and understand the requirements of dimensional and geometric tolerances on drawings, as well as their measurement methods, and is also a compulsory course.
Principles of Metal Cutting and Cutting Tools This is a course that tells you how to sharpen and select cutting tools, as well as choose the amount of cutting. （
The Principles of Metal Cutting and Tooling is a course that tells you how to sharpen and select tools, as well as choose the amount of cutting. (It may also be taught in CNC machining technology.
"CNC machining technology" is a comprehensive course in CNC, tell you how to process a part of the course, may cover some of the content of the previous books,
If you have a more systematic CNC machining technology book, according to the content of the book, omit some of the previous books.
"CNC machine tool programming and operation" as the name suggests is the machine tool programming and operation of the book, as long as there is a rigorous thinking, this book is not difficult to learn. Programming content is the macro program is a little difficult,
operation of the knife technology is the key.
In addition to learning the above courses, you also need to learn the manual of the CNC machine you operate.
In addition, some math foundation is needed, such as geometry, trigonometry, plane analytic geometry. It doesn't matter much if the math is poor,
because you can use AutoCAD to draw to get the coordinate values. Plane analytic geometry is basically a foundation for macro programs. You don't need to use it normally.
Then you can learn plane drawing software (to calculate coordinate values) and automatic programming software. Automatic programming software is used to program more complex drawings.
Question 4: Learn what basic knowledge of CNC machine tools to have What is CNC technology
CNC technology refers to the use of digital, text and symbols composed of digital commands to achieve one or more mechanical equipment action control technology. What it controls are usually mechanical quantities such as position, angle, speed, and switching quantities related to the flow of mechanical energy. Numerical control depends on the emergence of data carriers and binary forms of data operations. 1908, perforated metal sheet interchangeable data carriers were introduced; the end of the 19th century, paper as a data carrier and auxiliary functions of the control system was invented; 1938, Shannon in the U.S. Massachusetts Institute of Technology carried out a rapid operation and transmission of data, laying the foundation for modern computers, including computer numerical control systems. Foundation. CNC technology is closely integrated with the development of machine tool control. 1952, the first CNC machine tool was introduced, becoming an epoch-making event in the history of the world's machinery industry, promoting the development of automation.
Now, CNC technology is also called computer numerical control technology, it is currently the use of computers to achieve digital program control technology. This technology uses computers to perform the control function of the equipment according to the control program stored in advance. As a result of the use of computers to replace the original hardware logic circuits composed of numerical control devices, so that the input data storage, processing, arithmetic, logic judgment and other control functions can be achieved through computer software to complete.
CNC machine tool is a technology-intensive and high degree of automation of mechatronics processing equipment, is a comprehensive application of computers, automatic control, automatic detection and precision.... High processing accuracy, quality is easy to ensure that the development prospects are very broad, so it is particularly important to master the CNC lathe machining programming technology
The development trend of CNC machine tools

April 19 from the seventh China International Machine Tool Show was informed that, with the continuous development of science and technology, the development of CNC machine tools is also faster and faster, CNC machine tools are also moving towards high-performance, high-precision, high-speed, highly flexible and modular direction. High performance: With the enhancement of the integration of CNC systems, CNC machine tools also realize multiple centralized control, and even remote control over long distances. High precision: the precision of the CNC machine tool itself and the precision of the processed parts is getting higher and higher, and the precision should be well maintained. High speed: the speed of each axis of CNC machine tool operation will be greatly accelerated. High flexibility: the flexibility of CNC machine tools will be developed in the direction of a higher degree of automation, management, logistics and the corresponding auxiliary machine integrated flexible manufacturing system.

The following CNC expertise how to learn!
Question six: learning CNC to have what basic knowledge Mechanical drawing, tolerance and coordination, CNC programming, CNC machining and process.
Question 7: CNC machine tools to what foundation? What education? Do CNC basically rely on experience, ah, you to a smaller enterprise to try.
Question 8: CNC lathe zero basis how to learn If you want to learn systematically you must be able to look at the drawings, first of all, review the geometry and three-dimensional geometry you learned in school. Each thing from a different angle will look different, the eyes can see the general solid line drawn, can not see the general dotted line drawn. Understanding the drawings you also need to know where to start with this job. But I recommend that you first go to the CNC training institutions to learn, the tuition is about a thousand dollars or so. After learning you will know the initial knowledge, there are certificates can go out to do the operator, and so you have accumulated knowledge in all aspects of the almost then you can help people debugging machine tools.
Question nine: learn CNC just start need to learn what first? If the basis of machining already have, then the first step is to learn the principles of CNC, and then CNC machine coordinate system, and then learn the basic instructions of CNC programming, write a simple CNC program, learn CNC machine operation.
Related books are CNC Machining Processes, CNC Machine Programming and Operation.
When learning to operate, you also need a CNC machining simulation software.
