What is the core of the control operation of the CNC lathe

CNC devices are the core of CNC machine tools. The CNC wide key is mainly composed of three basic parts: input, processing and output. All of these tasks are organized by computer system programs so that the whole system works in harmony with each other.

1. Input equipment: input CNC instructions to CNC equipment, and there are different input devices according to different program carriers. There are mainly keyboard input, disk input, direct communication input for CAD and CAM systems, and DNC input connected to the host computer.

2. Processing device: The input device transmits the processing information to the CNC unit, compiles it into information that can be recognized by the computer, and the information processing part is stored and processed step by step in accordance with the provisions of the control program, and then the position and speed instructions are sent to the servo system and the main motion control part through the output unit. 3. Output device:

The output device is connected to the servo mechanism. The output device receives the output pulse of the combinator according to the instructions of the controller and sends it to the servo control system of each coordinate. After power amplification, the servo system is driven, so as to control the movement of the machine tool according to the specified requirements.

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.

Feedback and control - CNC machine tools know their theoretical position and actual position, and correct them through CNC systems, motors, etc., so that they are always in the best state.

1.Servo amplifier.

1) Power module: turn the AC point into direct current, and supply power to the spindle and servo module.

2) Spindle module: Convert the direct current of the power module into alternating current, and supply power to the spindle motor to receive NC command to control the spindle operation.

3) Servo module: Convert the direct current of the power module into alternating current, supply power to the servo motor, accept NC command, and control the operation of the servo motor.

4) IO interface: the interface between NC and the electronic components of the machine tool.

2.Spindle motor.

3.Servo motor.

4.Control panel.

Can you elaborate a little bit?

We don't know what kind of machine tool you are talking about, how to say it, to be specific, there may be more people, generally including: control software - with servo drive function, can identify iso**.

It also includes hardware circuits, such as signal transfers, motors, controllers, etc.

The control mode of industrial robot can be divided into non-servo control mode and servo control mode according to the control feedback mode, and can be divided into point servo control and continuous servo control according to the movement mode of the robot hand in space. Different industrial requirements have different control methods to match.
