【摘要】：近年来我国已成为木制品的生产大国，木结构建筑越来越受到人们的青睐，这也就对木结构件的生产技术和产品质量提出了更高的要求。实现木结构件模块化加工对提高木构件的生产效率和生产质量具有重要作用。为此我们需要研发出具有自主知识产权的，可进行木构件模块化加工的数控技术和设备。 本文基于前人的研究成果对五轴数控机床的坐标变换计算方法、刀具补偿和插补误差分析等进行了优化，使其更加的简洁明了且不失正确性。由于国内对木结构件模块化加工方面的研究较少，可供查阅的文献资料几乎没有，因此对于国内来说在这个方面的研究算是一个较新领域。 论文第一章介绍了木结构件模块化加工及数控技术在国内外的发展现状；第二章根据木工数控机床的基本功能要求搭建了运动控制实验平台；第三章完成了对五轴木工数控机床的刀具补偿算法和直线插补误差分析；第四章对运动控制系统的人机界面进行了设计开发；第五章对木结构件模块化加工、参数化设计以及G代码的自动生成方法进行了研究；第六章对论文的主要内容进行了总结和展望。 本研究的主要结果有： （1）完成了刀具补偿算法，对直线线性插补进行了误差分析，并可根据误差允许范围确定最少插补点数。 （2）利用C#语言和OpenGL技术结合SharpGL扩展库在VS2010平台上进行了运动控制系统人机界面的开发，并实现了可视化图形显示。 （3）为了提高生产效率、减少程序出错率，实现了木结构件模块化加工和参数化设计，并通过改变参数仿真了几个木结构零件。通过程序模块的编制，实现了通用G代码指令的自动生成方法，使其可以根据木结构件的几何参数自动生成相对应的G代码。
[Abstract]:In recent years, our country has become a big production country of wood products, and wood structure building has been more and more favored by people, which also put forward higher requirements for the production technology and product quality of wood structure parts. The realization of modular processing of wood structures plays an important role in improving the production efficiency and quality of wood components. To this end, we need to develop independent intellectual property rights, can be modular processing of wood components numerical control technology and equipment. Based on the previous research results, this paper optimizes the coordinate transformation calculation method, tool compensation and interpolation error analysis of five-axis CNC machine tool, which makes it more concise and accurate. Due to the lack of domestic research on modular processing of wood structures, there is little literature available for reference. Therefore, the research in this field is considered as a relatively new field in our country. The first chapter introduces the development status of modular machining and numerical control technology of wood structure parts at home and abroad. The second chapter builds an experimental platform for motion control according to the basic function requirements of woodworking CNC machine tools. The third chapter completes the tool compensation algorithm and linear interpolation error analysis of the five-axis woodworking numerical control machine tool, and the fourth chapter designs and develops the man-machine interface of the motion control system. In chapter 5, modular machining, parametric design and automatic generation of G code are studied, and the main contents of the paper are summarized and prospected in chapter 6. The main results of this study are as follows: (1) the tool compensation algorithm is completed, and the error analysis of linear interpolation is carried out, and the minimum interpolation points can be determined according to the error allowable range. (2) the man-machine interface of motion control system is developed on the VS2010 platform by using C # language and OpenGL technology combined with SharpGL extension library, and the visual graphic display is realized. (3) in order to improve production efficiency and reduce the error rate of program, modular machining and parametric design of wood structure parts are realized, and several wood structure parts are simulated by changing parameters. Through the programming module, the automatic generation method of general G code instruction is realized, which can automatically generate the corresponding G code according to the geometric parameters of wood structure.
