摘　　要：将一台由嵌入式SoC单片机控制的雕刻机,与基于PC机或DSP的雕刻机数控系统相比,其是一种低成本的解决方案。在给出了以C8051F120单片机为主控芯片的数控系统原理框图的基础上,进一步讨论了逐点比较法直线插补的基本原理,并对控制系统的主要软件功能作了说明。经测试运行,该系统雕刻精度达0.01 mm,且雕刻速度快,并具有一定的经济实用价值。In view of the wide application of the engraving machine,an embedded SOC microcontroller controlled engraving machine is developed. It is of less production costs than the engraving machines based on PC or DSP. The control system block diagram with the C8051F120 microcontroller as core processor is presented. The basic theory of the line interpolation using point-by-point comparison method is discussed. The system software function is also introduced. Practical tests show that the carving accuracy is 0. 01 mm. With fast carving speed,the design is of economic value.
