毕业设计说明书 课题名称普通X52k铣床的数控化改造（西门子802s数控系统） 系 别 电气工程系 专 业 机电一体化 班 级 机电0611班  普通X52K铣床的数控化改造（西门子802S数控系统） 摘 要 普通机床的数控化再制造，是一项可以节约大量的资金的新技术。通过对旧机床的数控化再制造后，使机床性能接近新的机床，提高了零件的加工精度，改善了工作环境，提高了劳动生产率，缩短了制造周期. 数控机床设计是一项多元组成的系统工程。系统的单元结合成，单元的功能不仅相互叠加，而且相互辅助、相互促进与提高，使整体的功能大于各单元功能的简单之和。 Ordinary X52K milling machine numerical control transformation (Simens 802S numerical control system) Abstract The ordinary engine bed numerical control makes again, is one item may save the massive fund new technology.Through makes again after the old engine bed numerical control, causes the engine bed performance close new engine bed, increased the components processing precision, improved the working conditions, enhanced the labor productivity, reduced the manufacture cycle. The numerical control engine bed design is one item the systems engineering which is composed by many units.Will combine to form through the systematic each unit another big system, not only will enable various units the function to superimpose mutually, moreover might make various units to assist, to promote and the enhancement mutually mutually, thus will cause the whole the function to be bigger than various units function the simple sum. This article main introduction engine bed numerical control transformation, the numerical control were the numerical control system, in the milling machine numerical control transformation the numerical control system choice, control the engine bed the mechanism, milling machine numerical control transformation electrical system aspects and so on design narrated the numerical control milling machine transformation.
