随着精加工技术的发展和数控机床的应用,高效率、高精度的测量仪也发展起来,三坐标测量机就是其中的一种。以前国内研制的测量机都配置小型计算机系统作为数据采集和数据处理工具。两年来,我们为SZC-543型三坐标测量机选配了包括两台5英寸软磁盘驱动器和一台行打印机的TRS-80微计算机系统来完成此项任务,使产品价格大为下降。为方便国内用户的使用和维修,我们在扩展I/O接口中全部采用了国内生产的大中小规模数字集成电路。试验证明:只要设计和调试工作做好了,国内器件同样可达到很高的稳定性和可靠性。目前,这套数据采集和数据处理系统正以跟小型机数据采集和数据处理系统同样的功能工作着。
With the development of finishing technology and the application of CNC machine tools, high efficiency and high precision measuring instruments have also developed. CMM is one of them. Before the development of domestic measurement machines are equipped with small computer systems as data acquisition and data processing tools. For two years, we’ve done this with the optional SZC-543 CMM, a TRS-80 microcomputer system that includes two 5-inch floppy disk drives and a line printer, resulting in a significant price drop. In order to facilitate the use and maintenance of domestic users, we have adopted all the Dazhong Xiao digital ICs in the expansion I / O interface. Test proved that as long as the design and commissioning work done, the same domestic devices can achieve high stability and reliability. Currently, the data acquisition and data processing system is working on the same features as the minicomputer’s data acquisition and data processing systems.
