Research On The Intelligent Control System Of Numeric Control WEDM Working Fluid Design

NC WEDM has played an important role in the automotive, aerospace and other precision machinery mold processing. At present, the LS-WEDM is going towards the direction of the development of high precision and speed. Working with high-precision wire-cutting process, the conductivity of working fluid affects the discharge effect, the temperature affects the deformation of the work piece, and thereby the problem has become a technical bottleneck which combined effects of cutting accuracy and quality of high-precision EDM. Therefore, it is very important to do the research which in the field of the working fluid conductivity and temperature in real time, on-line precision control research.This subject is focus on working fluid conductivity measurement and control of WEDM machine, via the measurement method of industrial water conductivity, as well as research and analysis in the industry fluid conductivity measuring machine factors. Based on innovative ideas, I am holding out a new method which used in a working fluid conductivity measurement, conversion, transmission, processing of wire-cutting machine. This subject used the DK7632-type LS-WEDM machine from Suzhou Sanguang Science and Technology Co., Ltd. as the research object. Doing the theoretical and experimental research and completing the design of intelligent control system of the working fluid of the NC WEDM machine. Through experimental study proves that the advanced nature and feasibility of the research. The major research paper is divided into six chapters as follows:Chapter I Overview. First of all, through the presentation of WEDM technological development, hold on the sources of subject; through the analysis of research in WEDM and on the aspect of working fluid control technology at home and abroad, Combined with our country current work on WEDM working fluid control technology, hold out the research subject which doing the intelligent control system design of NC WEDM working fluid. And I established a major research topic.Chapter II The model of intelligent control system of the working fluid. Based on the mechanism of conductivity measurement analysis about the working fluid, and combined with system processing mode, processing requirements, the state of fluid systems, build a new technology program in WEDM working fluid measurement, conversion, transmission, processing. By the scheme, I have built a fuzzy control method using the working fluid model of intelligent control system. Chapter III Hardware design. Build a program based on the technology and intelligent control system model, in view of the sampling system, transmission, anti-jamming performance of the executing agency and the actual requirements of the work, researching and designing the hardware platform for hydraulic intelligent control system.Chapter IV Software design. According to the control signal of liquid sample, combined with the intelligent control system model and the hardware platform has been designed, I developed the software of the intelligent control system under the compiler environment of using C + + language in Visual C + +, and run debug.Chapter V Experimental Study. Combining hardware and software systems of the intelligent system, installed to DK7632, controlled the working fluid. Through optimize and improve to the system parameters in experimental study, I have established objectives with successful completion. Research is turning to the industrialization.Chapter VI Summary and Outlook. Doing the summary of the main research and design about this article, and summary of the results from experimental studies and analysis, put forward the issues of inadequacy and a future direction for improvement.In this paper, there has some mainly innovations as follows:1. Holding out a new method in WEDM conductivity signal acquisition and processing, anti-transmission.2. Facing the problem of fuzzy phenomenon in conductivity measurement and control for the working fluid, using the combination methods of fuzzy control theory and electrical conductivity measurement, I established intelligent control systems model of the working fluid.3. Based on the model of the intelligent control system, I designed the hardware platform by using Protel software, developed the software of the intelligent control system under the compiler environment of using C + + language in Visual C + +, and run debug. And it leaded a experimental basis for another in-depth study.
