The Design Of A Master-slave System Of Economical CNC Drilling And Milling Machine Tool

This dissertation mainly introduces parallel communication of a master-slave system of three_coordinate printed circuit board numerical control drilling and milling machine tool. In order to use the abundant software and hardware resources of IPC and to compile software of system which is friendly to users, and in order to compile the control software of execution machinery by C and Assembly language at the same time, this CNC system adopts the master-slave structure and parallel communication method. The master computer sends control instructions and parameters to the slave computer under Windows98, for the sake of making the slave computer work well. This system enhances the expanse and open ability of the original CNC machine tools, and can strengthen function of compile system by the achievements in the field of computer software in the world. It is beneficial to importing drawing and well done to produce and analogy trace under dynamic state, and is favorable to measuring, compiling and producing at the same time. It makes compile become easy and efficient. This article expounds the integration structure and the rationale of the system and the ideas used in designing hardware and in compiling software. There are five principal parts in the full text: the summary of CNC and this CNC system; the design of the hardware and software of the slave computer; the introduce of IPC control system and electromotor; the communication port and mode between the the host computer and slave computer; the frame design of the host computer software.
