Summary. The electrical control system of the CNC machine tool is made up of:

Numerical control device. Feed servo system.

Spindle servo system.

Machine tool strong current control system.

The CNC device is the center of the electrical control system of the CNC machine tool, which can automatically process all the CNC machining programs input into the CNC machine tool, and at the same time divide these CNC machining programs into two categories of control quantities and output them separately.

In the electrical control part of CNC machine tools, there are three main logic circuits.

CNC machine tool electrical control leakage system by CNC device feed servo system spindle servo system machine tool strong electric control number volt system CNC device is the center of the CNC machine tool electrical control system, it can automatically input to the CNC machine tool inside all CNC machining programs for processing, while these CNC machining programs are divided into two categories of control quantities, respectively.

The first type is the continuous control quantity, which transports the old annihilation to the servo system; The second type is the discrete switching control quantity, which will be transmitted to the strong current control system of the CNC machine tool to serve the leakage.

SCM and IPC are two different types of computer components, with different characteristics and application scenarios.

A microcontroller usually refers to a microcontroller, which is a special integrated circuit chip that integrates functions such as processor, memory, input and output, and analog circuits. Single-chip microcomputers usually use single-chip integration technology, with relatively single functions, but have the advantages of small size, low power consumption and low cost. MCUs are mainly suitable for some relatively simple control tasks, such as Internet of Things devices, home appliance control, automotive electronics and other fields.

Industrial computer is a kind of industrial computer with large-scale data processing and high-performance computing capabilities, usually using multiple industrial-grade processor chips, with high computing performance, reliability and strong stability. The architecture of the industrial computer is similar to that of a regular computer, but the components and software used are all industrial grade, which can achieve stable operation in the industrial field environment. Industrial computers are mainly used in industrial control, robot control, logistics and warehousing, intelligent transportation and other fields.

In terms of application scenarios, single-chip microcomputers are suitable for some relatively simple control tasks, such as controlling motors, sensor acquisition, data storage and processing, etc. Industrial computers are suitable for industrial automation, logistics and warehousing, and intelligent transportation that require a large amount of data processing and high computing capabilities.

None of the above are complete.

The single-chip microcomputer, to put it bluntly, is a chip, which can handle some simple logic or its operations. We are commonly known as PLC, programmable controller, you can understand that its CPU is actually a single-chip microcomputer. The single-chip microcomputer can be used with others, such as the IO module, to form a similar function to the PLC, but its anti-interference ability is very poor, and it cannot be applied to the occasion where the electromagnetic environment is more complex.

You can plc.

Industrial computer, simply put, is the industrial computer, we generally say the computer, is the home computer, the difference between them is basically not big, mainly in the industrial computer, can be applied in industrial control, it can adapt to the complex electromagnetic environment, thermal stability and adaptability to humidity are better than the home computer, at the same time, it is relatively speaking, its hardware settings reserved port more, the industrial bus is different from the home computer, can adapt to the processing capacity of relatively large information, generally speaking, the same configuration of the industrial computer, than the home computer is more expensive.

Single-chip microcomputer and industrial computer are not the same kind of thing at all, single-chip computer at most computing industrial computer graphics card, or a certain chip on the motherboard, processor. Wild Hall.

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode programs with control codes or other symbolic instructions so that the machine can move and the parts are machined.

The operation and monitoring of the CNC machine tool are all done in this CNC unit, which is the brain of the CNC machine. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

High machining accuracy and stable processing quality;

It can carry out multi-coordinate linkage and process parts with complex shapes;

When the processed parts are changed, generally only need to change the CNC program, which can save production preparation time;

The machine tool itself has high precision and rigidity, and can choose a favorable processing amount, and the productivity is high (generally 3 5 times that of ordinary machine tools);

The machine tool has a high degree of automation, which can reduce labor intensity;

The quality requirements for operators are higher, and the technical requirements for maintenance personnel are higher.

CNC machine tools are generally composed of the following parts:

The main machine, which is the subject of CNC machine tools, includes mechanical components such as machine body, column, spindle, feed mechanism, etc. He is a mechanical component used to complete various cutting operations.

The numerical control device is the core of the CNC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and the corresponding software, which is used to input the digital part program, and complete the storage of input information, the transformation of data, the interpolation operation and the realization of various control functions.

The drive device is the driving component of the actuator of the CNC machine tool, including the spindle drive unit, the feed unit, the spindle motor and the feed motor. He implements the spindle and feed drive by means of an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, positioning, straight lines, plane curves and spatial curves can be processed.

Auxiliary devices, some necessary supporting parts of the index control machine tool, are used to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as tools and monitoring and testing devices.

Programming and other ancillary equipment can be used to program and store parts outside the machine.

Since 1952, the Massachusetts Institute of Technology developed the world's first CNC machine tool, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries.

CNC numerical control, of course, is controlled by numbers! Ha ha.

In the early days, single-chip microcomputers were all 8-bit or 4-bit. The most successful of these is Intel's 8031, which has received great praise for its simplicity, reliability and good performance. Since then, the MCS51 series MCU system has been developed on the 8031.

The microcontroller system based on this system is still widely used until now. Especially with the wide application of the ARM series, 32-bit single-chip microcomputers quickly replaced the high-end status of 16-bit single-chip microcomputers and entered the mainstream market. The performance of traditional 8-bit microcontrollers has also improved dramatically, and the processing power has increased by hundreds of times compared to the 80s.

At present, the main frequency of high-end 32-bit microcontrollers has exceeded 300MHz, and the performance has caught up with the dedicated processors in the mid-90s.

The main structure of the industrial computer.

1. All-steel chassis.

IPC's all-steel chassis is designed to the standard to resist shock, vibration, and electromagnetic interference, and can be fitted with a PC-BUS-compatible passive base plate.

2. a passive bottom plate.

The slots of the passive backplane consist of bus expansion slots. The bus expansion slot can be selected according to the user's actual application to expand the ISA bus, PCI bus and PCI-E bus, PCIMG bus of multiple slots, the number and location of the expansion slots according to the need to have a certain choice, but according to different PCIMG bus specification versions of various buses in the combination of requirements, such as the version bus does not provide ISA bus support, the board is a four-layer structure, the middle two layers are the ground layer and the power layer, This structure can reduce the mutual interference of the logic signals on the board and reduce the impedance of the power supply. The backplane can be plugged into various boards, including CPU cards, graphics cards, control cards, I.O cards, etc.

3. Industrial power supply.

In the early days, the industrial computers mainly used AT switching power supplies, and now they mainly use ATX power supplies like PCs, with an average trouble-free running time of 250,000 hours.

4. CPU card.

There are many kinds of CPU cards of IPC, which can be divided into long cards and half-length cards according to the size, and most of them use desktop system processors, such as 386 486 586 PII in the early days, and now the mainstream is P4, Core dual-core and other processors, and motherboard users can choose any according to their needs. Its main features are: working temperature 0-60; with hardware "watchdog" timer; There are also some CPU cards that require low power consumption that use embedded series CPUs.

The difference between the electrical control of CNC machine tools and the electrical control of ordinary machine tools:

Numerical Control (NC) technology is an automatic control technology that uses digital information for control; A machine tool controlled by numerical control technology, or a machine tool equipped with a main control system, is called a CNC machine tool. CNC machine tools are typical products of mechatronics, and modern CNC systems are also known as computer numerical control (CNC) systems.

Features of CNC machine tools:

A CNC machine tool is a machine tool with a program control system installed, which can logically process the instructions specified by the use of numbers or other symbolic encoding instructions. CNC machine features:

1) High machining accuracy: CNC machine tools are a combination of precision machinery and automation technology. The numerical control device of the machine tool can compensate for the errors caused by displacement and thermal deformation generated in the movement of the machine tool through the measurement system to obtain high and stable machining accuracy.

Because the CNC machine tool realizes automatic processing, it reduces the human error caused by the quality of the operator and improves the consistency of the same batch of parts.

2) Higher production: In terms of production efficiency, compared with ordinary machine tools, the efficiency of CNC machine tools can generally be increased by 2 3 times, or even more than ten times. It is mainly reflected in the following aspects:

a.Multi-process processing is completed in one clamping, which eliminates the need for multiple changes in the type of work, the transfer between processes, and the marking and other processes of ordinary machine tool processing.

b.Fixtures and special tooling are simplified, and processing is completed in a single clamping. Therefore, the multi-process fixture of ordinary machine tools is omitted, even if a special fixture is occasionally necessary. Due to the super function of the CNC machine, the structure of the fixture can also be simplified.

3) Reduce labor intensity, and the operation of CNC machine tools has changed from physical strength to intelligence.

4) Improve working conditions, such as Shenyang company's products use fully enclosed shields, machine tools will not have water, oil, iron filings splashed, can effectively keep the working environment clean 5) Conducive to production management

a.Convenient for programmed control processing and variety replacement;

b.One machine with multiple processes to reduce the management of the production process and reduce the management personnel; c.Unmanned production can be realized.

CNC machine tools have PLC (PMC) program control external relays or contactors inside, and do not want ordinary machine tools to be completely controlled by external interlocks and other designs.

The control design of CNC machine tools is more convenient and the action is more complex.
