【摘要】：随着后工业化时代浪潮的来临,客观上对生产力的进一步发展提出了迫切的需求。作为传统产业的代表,机械制造业在工业4.0变局中将会面临巨大的变革,这些变革将会彻底改造现有的产业布局。而作为机械制造的核心——数控机床技术毫无疑问的会发挥重要的作用。本文从KVC600立式加工中心入手,作为一体化加工中心的代表型号,研究其加工精度误差、运行可靠性,并以此提出改进建议,展望未来机床的发展趋势。本文主要工作为:1.本文对主要研究对象——KVC600立式加工中心的总体结构进行介绍,对数控机床加工误差的检测和分析方法进行探讨,结合国内外文献,得出本文通过双频激光干涉的方式测量机床加工误差是目前较为先进、有效而又兼顾性价比的方法,提出了对加工误差的处理分析方法和针对此的误差补偿方式。2.通过双频激光干涉仪对KVC600立式加工中心的误差进行各轴加载检测试验和工件加工实验,并进行分析补偿。3.通过对KVC600立式加工中心在不同使用场景中的实际工况故障进行长期跟踪,并运用软件对反馈数据进行归纳处理,据此通过可靠性分布公式推算机床平均无故障工作时间MTBF等可靠性指标,得到加工中心的运行可靠性结论。同时,本文还结合实验数据分析的结论探讨了加工中心的改进方法,提出未来的发展趋势。
[Abstract]:With the arrival of the tide of post-industrialization, there is an urgent need for the further development of productive forces. As the representative of the traditional industry, the machinery manufacturing industry will face great changes in the change of industry 4.0, which will completely transform the existing industrial layout. As the core of mechanical manufacturing-CNC machine tool technology will undoubtedly play an important role. Starting with KVC600 vertical machining center, as the representative model of integrated machining center, this paper studies its machining precision error and operation reliability, and puts forward some suggestions for improvement and prospects for the future development trend of machine tool. The main work of this paper is: 1. This paper introduces the overall structure of KVC600 Vertical Machining Center, discusses the methods of measuring and analyzing the machining errors of NC machine tools, and combines the domestic and foreign literature. It is concluded in this paper that the method of measuring machining error of machine tool by dual-frequency laser interference is more advanced, effective and cost-effective at present. The processing and analysis method of machining error and the error compensation method of this method are put forward. The error of KVC600 vertical machining center is tested by dual-frequency laser interferometer. Through the long-term tracking of the actual working conditions of KVC600 vertical machining center in different usage scenarios, and the use of software to sum up and process the feedback data, According to the reliability distribution formula, the average failure free working time (MTBF) and other reliability indexes of machine tools are calculated, and the operating reliability conclusion of machining center is obtained. At the same time, based on the conclusion of experimental data analysis, the improvement method of machining center is discussed, and the development trend in the future is put forward.
