A Technology of CNC Punching of Chinese Characters

Abstract:

The punching process with CNC is getting more and more important in the modern metal stamping field. But it is still difficult to realize NC punching the Chinese characters in manufacturing. Furthermore, it is expensive for processing forms of Chinese characters like thread cutting, laser cutting, etc. In addition, the ability to process the characters in a large size is restricted by the efficiency and the size of the machine. Therefore, this paper shows the details about programmable automation which is used in the characters processing on CNC punching machine. The content includes: getting the font parameter of character from DXF file, building the curve function for contour of characters, and creating G code for NC punching process. This technic provides a new method on processing big-size Chinese characters. And this technology can improve the efficiency and precision, and reduce the distortion of contour gotten by traditional program.
