摘   要
 随着现代科学技术的发展， 特别是近几年来汽车工业的腾飞，多楔带传动方式的优越性日益显露出来，其应用也越来越广，同时对多楔带的要求也越来越高。相对于国外的先进设备而言，目前国内许多中小型企业的多楔带磨削机在生产方式及生产效率上已显得落后，难以保证多楔带尺寸的精度。由于引进设备的昂贵，如能自制合格的多楔带，必将减小中小型企业的成本。由此可见，研制出一种低成本、功能全的多楔带磨削机具有很广阔的市场前景。
 本文主要介绍了以可编程控制器PLC为核心的多楔带磨削机控制系统的设计。根据多楔带磨削机的控制系统的要求，对模块及执行机构进行选型。在查阅相关文献^论文并分析了国内外设备的基础上，确定了控制系统的方案，该多楔带磨削机控制系统主要由三菱可编程控制器FX2N-32MR (主模块) 、FX2N-1PG-E(高速脉冲模块) 及步进电机驱动器组成等组成。同时进行了一部分软件的设计，对主体程序的各部分编写了相应的程序，最后对在软件的调试过程中所遇到的问题及解决办法进行了一定的说明。

Abstract
 With the development of modern science technology, especially automobile industry in the last few years, the superiority of driving by V-ribbed belt is revealing day by day and its application is also getting more and more broad, at the same time the request to the V-ribbed belt is also getting higher and higher. Compare with the sophisticated equipment overseas, the domestic enterprise especially many Small and medium-sized ones the V-ribbed belt milling machine already appears backward in the production method and the production efficiency, so its hard to guarantee the size and the precision of the V-ribbed belt at present. Because its expensive to import foreign equipments, a lot of money will be saved if enterprises can make a qualified  V-ribbed belt milling machine's thenselves, Thus it can be seen, develop a V-ribbed belt milling machine with complete function and low cost, will have a very bright future
 This article mainly introduces the designing of V-ribbed belt milling machine control system which used PLC as the main part, and the choicing of the main parts of the control system according to the request. After reading a many literature of science and technology and analyzing the foundation of both the domestic and foreign equipment, a design of the control system has come out. This V-ribbed belt milling machine control system is made up mainly by FX2N-32MR (main module), FX2N-1PG-E (high speed pulse module) and the step-by-step electrical machinery driver and so on. a part of software's design has be done too,and some of the program has been made up.

Key words：  V-ribbed belt; inding; PLC; control system
