嵌入式SoC单片机在雕刻机数控系统中的应用

摘要

In view of the wide application of the engraving machine , an embedded SOC microcontroller con-trolled 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 C 8051F120 microcontroller as core processor is presented .The bas-ic 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 .%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C8051 F120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。
