数控三轴运动控制实验平台设计

CNC Triaxial Motion Control Experimental Platform

针对国内数控技术起步较晚,核心技术受到限制,并且数控机床价格昂贵、体积大,并不适用于实验室、学校等场所的问题,笔者设计了一个基于GRBL的数控三轴运动控制实验平台。文中介绍了该平台的总体方案和软硬件设计,利用Solidworks软件对平台进行三维建模,为方案的可行性提供保障。通过Arduino实现对平台的控制,Visual Studio软件设计上位机GUI,Artcam软件设计雕刻模型并生成刀具的加工路径,最后用Matlab软件对插补原理进行了仿真分析。实验结果表明,平台成本低、体积小、控制高效,并成功实现绘制、雕刻功能。

In view of the late start of domestic CNC technology,the limited core technology,and the high price of CNC machine tools,large volume,not suitable for laboratories,schools and other places,the author designed a GRBL-based CNC three-axis motion control experimental platform.In this paper,the overall scheme and hardware and software design of the platform are introduced,and SolidWorks software is used for three-dimensional modeling of the platform to provide guarantee for the feasibility of the scheme.The platform was controlled by Arduino,the upper computer GUI was designed by Visual Studio software,the carving model was designed by ArtCAM software and the machining path of the cutter was generated.Finally,the interpolation principle was simulated and analyzed by MATLAB software.The experimental results show that the platform has the advantages of low cost,small volume,high control efficiency and successful rendering and engraving functions.
