【摘要】：近年來(lái)我國(guó)已成為木制品的生產(chǎn)大國(guó)，木結(jié)構(gòu)建筑越來(lái)越受到人們的青睞，這也就對(duì)木結(jié)構(gòu)件的生產(chǎn)技術(shù)和產(chǎn)品質(zhì)量提出了更高的要求。實(shí)現(xiàn)木結(jié)構(gòu)件模塊化加工對(duì)提高木構(gòu)件的生產(chǎn)效率和生產(chǎn)質(zhì)量具有重要作用。為此我們需要研發(fā)出具有自主知識(shí)產(chǎn)權(quán)的，可進(jìn)行木構(gòu)件模塊化加工的數(shù)控技術(shù)和設(shè)備。 本文基于前人的研究成果對(duì)五軸數(shù)控機(jī)床的坐標(biāo)變換計(jì)算方法、刀具補(bǔ)償和插補(bǔ)誤差分析等進(jìn)行了優(yōu)化，使其更加的簡(jiǎn)潔明了且不失正確性。由于國(guó)內(nèi)對(duì)木結(jié)構(gòu)件模塊化加工方面的研究較少，可供查閱的文獻(xiàn)資料幾乎沒(méi)有，因此對(duì)于國(guó)內(nèi)來(lái)說(shuō)在這個(gè)方面的研究算是一個(gè)較新領(lǐng)域。 論文第一章介紹了木結(jié)構(gòu)件模塊化加工及數(shù)控技術(shù)在國(guó)內(nèi)外的發(fā)展現(xiàn)狀；第二章根據(jù)木工數(shù)控機(jī)床的基本功能要求搭建了運(yùn)動(dòng)控制實(shí)驗(yàn)平臺(tái)；第三章完成了對(duì)五軸木工數(shù)控機(jī)床的刀具補(bǔ)償算法和直線(xiàn)插補(bǔ)誤差分析；第四章對(duì)運(yùn)動(dòng)控制系統(tǒng)的人機(jī)界面進(jìn)行了設(shè)計(jì)開(kāi)發(fā)；第五章對(duì)木結(jié)構(gòu)件模塊化加工、參數(shù)化設(shè)計(jì)以及G代碼的自動(dòng)生成方法進(jìn)行了研究；第六章對(duì)論文的主要內(nèi)容進(jìn)行了總結(jié)和展望。 本研究的主要結(jié)果有： （1）完成了刀具補(bǔ)償算法，對(duì)直線(xiàn)線(xiàn)性插補(bǔ)進(jìn)行了誤差分析，并可根據(jù)誤差允許范圍確定最少插補(bǔ)點(diǎn)數(shù)。 （2）利用C#語(yǔ)言和OpenGL技術(shù)結(jié)合SharpGL擴(kuò)展庫(kù)在VS2010平臺(tái)上進(jìn)行了運(yùn)動(dòng)控制系統(tǒng)人機(jī)界面的開(kāi)發(fā)，并實(shí)現(xiàn)了可視化圖形顯示。 （3）為了提高生產(chǎn)效率、減少程序出錯(cuò)率，實(shí)現(xiàn)了木結(jié)構(gòu)件模塊化加工和參數(shù)化設(shè)計(jì)，并通過(guò)改變參數(shù)仿真了幾個(gè)木結(jié)構(gòu)零件。通過(guò)程序模塊的編制，實(shí)現(xiàn)了通用G代碼指令的自動(dòng)生成方法，使其可以根據(jù)木結(jié)構(gòu)件的幾何參數(shù)自動(dòng)生成相對(duì)應(yīng)的G代碼。
[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.
