数控铣床XY工作台与控制系统设计 123 摘 要 随着现代信息技术的发展，以提高产品加工的生产效率为主的高度自动化和提高产品质量为主的精密化成为现代机械加工技术发展的两个主要方向。人们对数控机床、精密仪器和仪表以及各种精密机械设备提出了越来 的精度要求，X-Y工作台是这些设备实现高精密加工的重要部件，对于提高产品的加工起着尤为重要的作用。 本论文针对铣床工作台机构及其控制系统进行设计，主要包括伺服电动机的选型，滚珠丝杠的选型、强度校核及生产设计中应注意的问题,连接伺服电机和滚珠丝杠副的联轴器的选型，导轨的设计。根据系统的功能要求，选择数控系统的CPU，同时还需要扩展程序存储器、数据存储器以及步进电机驱动电源的选择。通过对工作台机械传动链的系统设计以期满足机床进给系统的定位精度和静动态性能，从而确保机床的加工精度。 关键字：X-Y工作台 ，伺服系统， 滚珠丝杠 ，步进电机  The design of CNC milling machine system XY workbench and control system Abstract With the development of modern information techniques, the high automation with the main purpose of improving the production efficiency of product process and the accuracy with the accuracy with the main aim of improving the quality of product have been becoming the two major directions of the modern technique of mechanical process. People on the CNC machine tools, precision instruments and meters and all kinds of sophisticated machinery and equipment raised higher and higher precision, X-Y workbench is that important components of these high-precision machining equipment to achieve the core components, for improving the quality of processed products play the particularly important role. The entire mechanical transmission chain for the system design,servo motor related to the selection, the selection of ball screws, checking strength and production design should pay attention to the problem of connecting the servo motor and the ball screw of the axis. The Telection and Verification, bearing pieces bearing the design, rail and rack design. According to the function requirement of system, the selection of the CNC system CPU. It would also need to expand the program memory、data memory and the choice of stepper motor drive power.Through the table mechanical transmission chain system design to meet the machine into the system to the positioning accuracy and static and dynamic performance, so as to ensure the accuracy of processing machine. key words：The X-Y workbench ; Servo system; Ball screw;stepper
