Abstract


The numerical control technology is a new manufacture technology which is the collection of traditional machine manufacture technology, the computer technology, the group technology, the modern control technology, the sensing technology, the information-processing technology, the hydraulic pressure and air-operated technology and the light-mechanical-electrical technology. In recent years, as the Internet technique rapidly developed, it melts into the network communication technology and breaks the regional limit of traditional processing, which paved the way for the realization of coordinating the design with the manufacture in different places, at the same time, it puts forward new requests for the manufacture process. However, some current CAD/CAM software are used in single computer, which are unable to achieve the request for the coordination of design in different places as well as the implementation of network processing.This article takes the common numerical control system FANUC-0 and its series as the research targets, taking the advantages of the embedded serial interface RS-232C used for communication, MATLAB7.1 for development kit, and also it conducts several researches as following:(1) Taking the MATLAB7.1 as develop platform, we carry on the design of customer interface and the functional simulation of CAD/CAM, where we strengthen the drawing of draft, and also we develop automatic programming software of numerical control processing.(2) We develop the communication interface between computer and FANUC-0 numerical control system; transport the numerical control code file by JAVA SOCKET technique.(3) Transform the graphic file produced by other CAD software into the DXF, then put into the MATLAB variable space by JAVA inputstream, so we can share the existing resources.(4) By the numerical control processing simulation with CAM, we deal with the CAD graphics and generate the numerical control code. Then save the code into text by JAVA outputstream, which is prepared for the long-distance transmission. Finally, according to the research achievement, we develop successfully the automatic programming system based on network, and give an application example to prove the correct and feasibility of design algorithm.
