Carving machine has great significance for modern industry, so study carving machine has certain significance. Carving processing involved in all walks of life, has a gift industry, the advertising industry, the seal industry, wood processing industry, construction industry, art, model industry, mechanical processing, tooling and etc, because of engraving machine is widely used, with the development of the society, the engraving machine industry's development is also inevitable, therefore, innovation of carving technology is very necessary. First is to analyze carving machine overall structure, carving machine generally consists of X, Y,Zof three axis and spindle, X, Y,Z three axis movement isa movement by stepper motor drive screw, main shaft through the motorized spindle drive tool motion. First of all to the overall control system design, ponent choice, circuit design. This paper studies the three-dimensional carving machine control system design, PLC control. Using the PLC of Siemens S7300 series. Choose good after ponents, connection diagram, design control circuit. This design is to adopt PLC control, so must be PLC programming. Use of software for the STEP7, respectively to the X, Y,Z three axis stepper motor to control,
