轴类零件数控加工工艺分析大学学位论文.doc

摘要 由于数控机床综合应用了电子计算机、自动控制、伺服系统、精密检测与新型机械结构等方面的技术成果，具有高的高柔性、高精度与高度自动化的特点，因此，采用数控加工手段，解决了机械制造中常规加工技术难以解决甚至无法解决的单件、小批量，特别是复杂型面零件的加工，应用数控加工技术是机械制造业的一次技术革命，使机械制造的发展进入了一个新的阶段，提高了机械制造业的制造水平，为社会提供高质量，多品种及高可靠性的机械产品。 本次设计主要是对数控加工工艺进行分析与具体零件图的加工，首先对数控加工技术进行了简单的介绍，然后根据零件图进行数控加工分析。 关键词轴类零件；数控加工；工艺分析；加工程序 Abstract With the rapid development of computer technology, the traditional manufacturing industry began a fundamental change, the industrial developed countries invested heavily in research and development of modern manufacturing technology, and put forward a new manufacturing model. In modern manufacturing system, the numerical control technology is the key technology, which combines microelectronics, computer, information processing, automatic detection, automatic control and other high technology in one, with the characteristics of high precision, high efficiency, flexibility and automation, the manufacturing industry plays a decisive role to realize flexible automation, integrated, intelligent. In this paper, through the analysis of the typical shaft parts of the process, from the drawing analysis, the clamping scheme, processing route, cutting tool selection, cutting parameter selection, machining process and other aspects of the numerical control turning process is described in this paper. Because the technology of CNC machine tool of comprehensive application of computer, automatic control, servo system, precision detection and a novel mechanical structure and so on, with high flexibility, high precision and high automation features, therefore, by means of NC machining, solves the problem of mechanical manufacturing in the conventional processing technology is difficult to solve the single, even can not be solved small batch processing, especially for complex workpieces, a technology revolution of CNC machining technology is the machinery manufacturing industry, the development of machinery manufacturing has entered a new stage, to improve the manufacturing level
