Brief introduction of CNC machine tool CNC device hardware, software composition.

Answer:

CNC (CNC machine) is a computer numerical control machine (Computernumericalcontrol) referred to, is a program controlled by the automation machine. The control system can logically process the program with the control code or other symbol instruction, decode it by the computer, so that the machine can perform the prescribed action, and the blank material is processed into semi-finished finished parts by cutting tool. Google Wikipedia has a specific inside. You can go and have a look. Quite detailed
CNC system generally by the input and output devices, numerical control devices, programmable controllers and other components. 1. The input / output device input device can transmit different processing information to the computer. In the early days of the production of CNC machine tools, the input device for the perforated tape, has now become out; at present, the use of the keyboard, disk, etc., greatly facilitate the information input work. Output refers to the output of internal operating parameters (including the machine is normal, the ideal working conditions of the original parameters, fault diagnosis parameters, etc.), the general work in the machine just to output these parameters for record and save, to be a period of time, then the output and the original Data for comparison, control, can help determine whether the machine work to maintain normal. . numerical control device (CNC) numerical control device is the core of CNC machine tools and lead, to complete all the processing data processing, computing work, and ultimately the NC machine tool functions of the command work. It contains microcomputer circuit, a variety of interface circuits, CRT monitors and other hardware and the corresponding software. . the programmable controller that PLC, it is the spindle unit to achieve control, the program speed command to control the spindle speed; management tool library, automatic tool exchange, the election method, the cumulative number of tools, tool life And the number of tool grinding and other management; control the spindle reversing and stopping, quasi-stop, cutting fluid switch, chuck clamping release, the robot handle knife and other actions; also on the machine external switch (limit switch, Control switch, etc.) to control the output signal (knife, robot, rotary table, etc.) to control.
