What is the role of the numerical control device of the prototype model? What is the carrier of prototype model information?

(1) The control medium

The control medium is the carrier that stores the information of the prototype model of CNC machining, it can be perforated tape, tape and disk, etc. CNC machining information includes the machining procedure of the part, when processing the part, the position of the tool relative to the workpiece and all the action control instructions of the machine tool, etc. They are recorded in the information carrier according to the specified format and code, that is, on the control medium.

(2) The numerical control device

The Numerical control device is the core of the numerical control machine tool, and the modern numerical control machine tool adopts computer numerical control (CNC)Device. The numerical control device is generally composed of three parts: input, information processing and output. Control media through the input unit ( Such as hole-piercing reading machine, tape drive, tape reader, etc) Input, converted into identifiable information, and the information processing unit processes the received information in accordance with the provisions of the program (Such as interpolation calculation, tool compensation, etc) After that, the prototype model sends out the position, speed and other instructions to the servo system through the output unit, thus realizing various control functions.

(3) The servo system

The servo system is to put various instructions from the numerical control device, the prototype model is converted into the driving part of the machine tool's execution mechanism movement. It includes spindle drive unit, feed drive unit, spindle motor and feed motor, etc.
