What is numerical control system

English name is: Numerical Control System Definition: can be controlled according to the numerical information instructions of the parts processing program , a control system that enables machine tools to complete work movements and process parts.

CNC system is the abbreviation of digital control system (Numerical CoNtrol System), according to the control program stored in the computer memory, it performs some or all numerical control functions, and is equipped with interface circuits and servo drive devices.

CNC system is the core of automatic machining of machine tools. It is mainly composed of operating system, main control system, programmable controller, various output interfaces, etc. Among them, the operating system is composed of a monitor and a control keyboard. The monitor has a variety of forms such as digital tube, CRT, liquid crystal and so on.

CNC system CNC system is the abbreviation of digital control system. The English name is Numerical Control System. In the early days, it was composed of hardware circuits and was called Hard NC. After the 1970s, hardware circuit components gradually It is replaced by a dedicated computer called a computer numerical control system.

CNC is an NC system that uses a dedicated program computer to perform some or all of the basic digital control functions.

CNC is an automated method of programming and controlling a work process with the help of numbers, characters or other symbols. CNC generally uses general or dedicated computers to realize digital program control, so numerical control is also known as Computer Numerical Control, abbreviated as CNC.

Operation steps of CNC lathe

1. Pull the power supply main switch to ON; press the NC system power supply ON switch on the main operation disk; after the system starts, release the emergency stop and press the reset key (RESET), then adjust the mode selection switch to the return to the original position and then press the three-axis return key (A.REP) until the three axes of XYZ return to zero and the power is completed.

2. If the input program needs to be modified, it should be edited. At this time, put the mode selection switch in the EDIT position, and use the edit key to add, delete and change. The machine tool is locked and the program is run. This step is to check the program. If there is an error, it will be edited again.

3. Manual programming operation The compiled processing program is input into the numerical control system. The specific operation method is: first start the CNC machine tool through the mechanical operation panel, then input the processing program from the CRT/MDI panel, and then run the processing program.

4. First, move the knife holder to the safe position in manual mode and press (edit key) and press (program key) to display the program screen.Then press (reset key) to move the cursor to the first line of the program, press (automatic processing key); press (loop start key).

5. Firmly grasp the functions of each operation button of the machine tool: know how to execute the program; how to pause the program and check the processing status of the workpiece, restore the pause state and continue to execute the program, how to stop the program; how to change the program before executing the program, and so on.

What kind of operating systems does CNC machine tool have

The CNC operating system I know include FANUC numerical control system; SIEMENS CNC system; Huazhong CNC system ; Century Star CNC System; Mitsubishi CNC System, etc. The FANUC numerical control system is relatively stable, while the operation interface of SIEMENS numerical control system is relatively friendly and easy to use.

Japan's FANUC numerical control system is made by Japan's Fana scientific research. The operation panel is simple and easy to understand, the system is of high quality, the performance is strong, the function is perfect, the market share is high, and it has a wide range of uses. It is a common CNC machine tool operating system in the workshop.

Siemens CNC system produced by Siemens in Germany;Mitsubishi CNC system produced by Mitsubishi Corporation of Japan; KND numerical control system produced by Beijing Kanedi (KND) Company; GSK numerical control system produced by Guangzhou CNC (GSK) Company.

Guangshu 980 is a CNC lathe system, which can only be used for lathes. Guangshu 980 is a self-developed system in China, which is completely different from other systems. There are many models such as 928T, 928TA, 928TC, 980T, 980TA, 980TC, 980TD, 980TDA and so on.

According to the control method of the servo system, the numerical control system can be divided into the following categories: (1) Open-loop control numerical control system This kind of numerical control system does not have a detection device or a feedback circuit, and the stepper motor is the driving component.

Such as FANUC16i/18i, Simens840D, NumIO60 and other numerical control systems.

How to make the operating system of CNC machine tools

The programming and operation of CNC machine tools mainly include the following steps: formulate a processing plan: according to product requirements and machine tool performance, formulate a processing plan, determine the tool, Fixtures and processing parameters, etc. Write processing programs: Use numerical control programming software on the computer to write processing programs, including G code and M code.

Processing program carrier: The parts processing program is stored on a program carrier in a certain format and code, such as perforated paper tape, cassette, floppy disk, etc., and the program information is input into the CNC unit through the input device of the CNC machine tool.

The position detection device detects the actual displacement of each coordinate axis of the CNC machine tool. After the feedback system is input into the CNC device of the machine tool, the CNC device compares the actual displacement value feedback back with the set value, and the control drive device moves according to the set value of the instruction.

Open numerical control system, such as motion control card, card manufacturer has a writing interface API, which needs to develop its own interface, function and logic. Generally use C language, C, VB, C#, etc. "CNC" in the numerical control system refers to G00, G01, etc., also known as encoder. It is originally not in the open numerical control system, and you need to write your own encoder.

Five commonly used numerical control systems in ChinaWhat are they?

1. The commonly used numerical control systems in China mainly include: Huazhong CNC, Aerospace CNC, Guangshu CNC, Comag CNC and Fanaco CNC, etc. First of all, Huazhong CNC occupies an important position in the field of domestic numerical control, and its Huazhong Type 8 series CNC system has been widely used in the machine tool industry.

2. Guangshu 980 Guangshu 980 is a CNC lathe system, which can only be used for lathes. Guangshu 980 is a self-developed system in China, which is completely different from other systems. There are many models such as 928T, 928TA, 928TC, 980T, 980TA, 980TC, 980TD, 980TDA and so on.

3. Traditional special CNC system, the hardware of this kind of CNC system is produced by the CNC system factoryIt is self-developed and has strong special purpose. After a long time of use, the quality and performance are stable and reliable. At present, it still occupies most of the market in the manufacturing industry.

What parts does the CNC system consist of? What is the function of each?

It is composed of input/output interface lines, controllers, operators and memory and other parts. The function of the numerical control device is to input the data input by the device through the internal logic circuit or control software.Compile, calculate and process, and output various information and instructions to control the specified actions of each part of the machine tool.

CNC device (CNC unit) composition: computer system, position control board, PLC interface board, communication interface board, special function module and corresponding control software.

The basic components of CNC machine tools include processing program carriers, CNC devices, servo drive devices, machine tool bodies and other auxiliary devices. When the CNC machine tool is working, there is no need for workers to operate the machine tool directly. To control the CNC machine tool, the processing program must be compiled.

The core of the CNC system is the CNC device. Due to the adoption of computers, the performance and reliability of CNC devices have been improved, which has promoted the rapid development of the CNC system.
