In this dissertation , the general development situation of the mrf machine tool and cnc system are reviewed firstly , and the development and current research work of cnc and ultra - precision machine tool control strategy are summed up 本文首先综述了国内外磁流变抛光技术和数控系统的发展状况,对数控系统及超精密机床控制策略的发展和研究状况进行了总结。
And now we finish the step - nc file . in the process of designing post - processor , our aim is converting step - nc file to some type cnc control code , and in this way verifying the step - nc file gained from pre _ processor 在后处理器的设计中，我们的主要目的是把step - nc文件转换成某种类型的数控机床控制系统的数据指令，以此来验证前处理器中得到的step - nc文件的正确性。
Our nc control unit has two type : sbc control unit and cnc control unit . the cnc control unit has yh , hf , hl , pm - k system etc that are easy to operate and have powerful function . the cnc control unit can match desk and cabinet type 我公司线切割机床控制部分有单板机和编控一体两大类，其中编控一体有yh 、 hf 、 hl 、 pm - k等编控系统供选择，编程操作方便，功能强大，同时有台式和立柜两种供选择。
In numerical control , data concerning all aspects of the machining operation , such as locations , speeds , feeds , and cutting fluids , are stored on magnetic tape , cassette , floppy or hard disks , or paper or plastic ( a thermoplastic polyester ) 在数控中，关于机床控制所有方面的数据，例如位置、速度、流动、流体分流、存储在磁带，软盘或硬盘，或者是纸，或者是塑料（一种热塑性的聚酯） 。
Abstract : some main problems of the superhigh speed nc machine tools , such as superhigh speed spindle vector controller , servo system of quick - response , reduced instruction set and other auxiliary functions in superhigh speed cutting are introduced in the paper 文摘:介绍了超高速数控机床控制系统的几个主要方面：超高速主轴矢量控制器、快速响应的伺服系统、精简指令集计算机系统及超高速切削中的其他辅助功能。
The diploma project researches the three - coordinate nc system of the boring and milling machine . the system must depend on the hardware - ipc ( industry personal computer ) and on the windows software . the hardwares have the framework of embedding nc in pc , which means that the hardware is composed of ipc , the intelligent sport control card ( pcl - 839 ) and the i / o card ( pcld - 782 / 785 ) . we research the nc system based on the operating system of dos and develop it into the nc system based on the operating system of windows2000 . the new nc system will do better for the three - coordinate nc machine tool than the old one 本文是以本学院自行研制开发的印制电路板钻铣床为研究对象,以工控机为硬件平台,以windows为软件平台,硬件系统采用“ nc嵌入pc式”结构,即运用现有的工控机+运动控制卡+数字量输入输出卡的基本结构,把机床控制系统开发成基于windows环境下的数控系统,代替原有的基于dos操作系统下的控制系统,从而实现对三坐标数控钻铣床的控制。
According to characteristic of parallel mechanism and the different control rule between traditional nc machine and parallel nc machine , the cnc system with open modular architecture has been set up . because the software module and hardware module have been designed based on standardization and diversification , the deviser can set up system with different module such as building block 根据并联实验平台的结构特点以及它与传统机床控制规律的不同，本文采用开放式、模块化体系结构建造数控系统，在标准化与多样化的基础上设计了软、硬件模块，这样就可以通过加减配置不同的模块来构造数控系统，实现系统“积木式”的集成。
It ' s made up of all the technologies such as computer , automation , electric drive , measurement and manufacturing . as the key technology of cims and fa , it is the advanced technology of manufacturing of the world . it makes the basis of machine tool industry and improves the international competitionablity of manufacturing industry 计算机数字控制技术是从20世纪70年代开始发展起来的机床控制新技术，它综合了计算机、自动控制、电气传动、测量及机械制造等各种技术，是计算机继承制造系统( cims )和工厂自动化( fa )的关键技术之一，是振兴国家机床行业、增强制造业国际竞争能力基础。
