Abstract: In order to keep up with the pace of social development,the reform of engineering training experience in colleges and universities,from the traditional metalworking center to the modernization of engineering training center conversion,from conventional practice training to engineering practice teaching conversion,from ordinary machine equipment to advanced computer numerical control( CNC) machine tools,CNC machine tools are also gradually replace the ordinary machine.In this paper,based on the engraving and milling strengthening training ( relief production ) of Zhejiang University engineering training center,according to the curriculum arrangement and operation process of CNC engraving in engineering practice teaching,combined with the characteristics of CNC carving,the specific application of CNC carving in engineering practice teaching was elaborated.
