The working principle of CNC Router

The computer numerical control cnc router is actually a three-dimensional numerical control system, and its working principle is shown in the figure:

A specialized design and typesetting software is installed in a general-purpose microcomputer for graphic and text design and typesetting, automatically generating machining path information. The tool path data is transmitted to the microcontroller through a USB interface or other data transmission interface. The CNC system receives the tool path data, completes a series of functions such as display and user interaction, and uses specific algorithms to convert the input path information

For numerical control information, the controller converts this information into signals (pulse trains) that drive stepper motors or servo motors, and controls the cutting of the X, Y, and Z axes of the cnc router. Simultaneously milling can carve various flat or three-dimensional graphics and text designed on the computer, achieving automation in carving.

Moreover, with the continuous emergence of various new decorative materials, there are more and more materials that can be used for carving, which provides greater opportunities for computer numerical control carving machines. Therefore, the application scope of computer numerical control carving machines will continue to expand.
