What Is CNC Precision Machining?

What does a CNC system consist of?

The CNC system consists of a processing program, input and output devices, a CNC device, a programmable controller (PLC), a spindle drive device, and a feed drive device.

The CNC system automatically processes the workpiece in strict accordance with the CNC program. The CNC processing program records various information required for machine tool processing in the order of part processing, such as the trajectory information, process information, and switch commands of part processing.

What is the working process of the CNC processing system?

The working process of the CNC device is the process of executing software with the support of hardware. 

The working principle of the CNC device is: various data information (CNC processing program) required for machine tool processing parts is input through the input and output devices, and after computer decoding, tool radius compensation, acceleration and deceleration control, interpolation and other processing and calculations, the moving component of each coordinate axis is sent to its corresponding drive circuit, and after conversion and amplification, the servo motor is driven to drive the coordinate axis to move, and real-time feedback control is performed at the same time, so that each coordinate axis can accurately move to the position required by the instruction. Thereby realizing the relative movement of the tool and the workpiece, the processing of the parts is automatically completed.
