西门子802D系统在数控铣床电气改造中的应用

Application of Siemens 802D System in Electrical Transformation of NC Milling Machine

介绍基于SINUMERIK 802D Solution Line数控系统的传统铣床电气改造方案。电气改造的目标是充分利用已有的机床机械本体并结合功能需求重塑其控制系统电气结构,提高机床加工精度及稳定性并令其满足数控教学和制造加工的需要。为此重新设计了机床的电气控制系统,新增了部分数控系统PLC程序,完善了机床的功能。经验证,改造后的数控铣床功能完善、运行可靠,可为此类机床的升级改造提供一定的参考作用。

This paper introduces a traditional milling machine transformation program based on SINUMERIK 802D Solution Line NC sys- tem. The transformation aims to fulfill the needs of both manufacturing and NC teaching, and improve the machining precision and stability of the machine tool by taking full advantage of its original mechanism. The electrical system and PLC programs are particularly redesigned for this object. It is proved that the transformed NC milling machine has perfect functions and high relia- bility, providing useful reference for the transformation of this type of machine tools.
