X5032立式铣床的数控化改造
摘要
数控铣床是当今制造业中实现机电一体化的代表性先进设备。本文在叙述了数控技术的历史、现状和发展的基础上，通过对国内外数控系统的比较，遵从性价比高、综合成本低的原则，最后确定采用SIEMENS 802S数控系统。针对SIEMENS 802S系统的特点和旧机床的要求，进行了电气系统的数控化改造设计、数控系统、电气伺服驱动系统的设计。电气部分分别对强电和弱电进行了改造，应用变频器对主轴电机进行控制，实现宽的调速范围，进给部分增加步进驱动器及步进驱动电机，实现数控化控制。通过对机床数控伺服驱动系统的接口匹配与连接，各项参数的设定和PLC程序编写，实现机床电气控制。并且，对所编写的PLC程序进行了仿真。最后阐述了改造后机床的精度和性能以及今后尚需完善之处。
机床改造后，显示了机床强大的工作能力和高度的可靠性，加工精度和生产率有较大提高，是提高企业数控化率的一条切实可行的途径。

CNC VERTICAL MILLING MACHINE X5032
TRANSFORMATION
ABSTRACT
CNC milling machine is currently manufacturing the representation of mechanical and electrical integration of advanced equipment. This paper describes the numerical control technology, history, current situation and development, based on the numerical control system through the comparison of domestic and foreign, to comply with cost-effective, integrated the principles of low cost, and finally determined by SIEMENS 802S CNC system. SIEMENS 802S system for the characteristics and requirements of the old machine to carry out the transformation of the NC electrical system design, numerical control systems, electrical servo drive system. Electrical part of the strong and weak electricity respectively were made, the drive for the spindle motor control applications, to achieve wide speed range, the feed part of the increase stepper driver and stepper drive motor, the NC Control. By the parameter setting and the PLC program, completed the CNC servo drive system interface matching and connection, the electrical control machine tool.Moreover, the PLC program for the preparation of a st modified machine described the accuracy and performance, and the future still need improvement.
After the transformation machine, showing a strong ability to work the machine tool and high reliability, precision and productivity has improved greatly, is to improve the corporate rate of NC a practical way.
