The working principle of computer engraving machine

1. Design and layout: Design and layout through familiar software (AutoCAD, Photoshop, Illustrator, CorelDRAW, 3dmax, ZBrush, Maya, Rhino) or special engraving software.

2. Import the designed file into the special engraving software, select the processing method and tool you need, and convert the file into processing data in the format of G code that can be read by the engraving machine controller.

Commonly used import formats are:

Vector: *plt,*eps,*dxf,*ai 

Three-dimensional: *stl,*obj,*igs

3. Import the processing data into the controller of the engraving machine, and then convert it into a signal (pulse train) with power that can drive a stepper motor or a servo motor, and control the X, Y, Z three-axis or multi-axis engraving movement of the engraving machine host . At the same time, the high-speed rotating spindle on the engraving machine cuts the processing material fixed on the worktable of the engraving machine through the tools configured according to the processing material, and can engrave various flat or three-dimensional relief graphics and characters designed in the computer. , To realize the automation of engraving operations. Important: Before automatic processing, the work origin must be manually set.

4. Commonly used engraving software: Wentai engraving software, Jingdiao, TYPE3, ARTCAM, etc.

5. Commonly used processing methods are: cutting, intaglio carving, positive carving, relief carving, three-dimensional carving, etc.

Cutting: It can also be called hollowing, which removes the required patterns or text from the board, or removes unnecessary ones.

Intaglio: a method of engraving the desired pattern or text into a recess.

Yang engraving: The engraving method that protrudes the desired pattern or text.

Relief: Up and down flat engraving method.

Three-dimensional sculpture: also called round sculpture, it can be carved in 360 degrees.

6. Commonly used engraving machine control systems include: Shanghai Weihong, DSP handle, Taiwan new generation and so on.

7. Commonly used processing data path formats are: *.nc, *.eng, *.mmg, *.u00, etc.
