The Mechanical Design Of The Metallographic Sample Cutting Machine And The Study On Its Controlling System

The Metallographic Sample Cutting Machine is mainly used to cut the metallographic sample and the metal stick or make slot in metal material , which make the machine widely used in machinery > metallurgy > automobile and aviation etc. With the development of science and technology in our country and the joining in the WTO, the machine will develop with the development of industry. As a kind of sampling equipment, the Metallographic Sample Cutting Machine will face more opportunity and challenge, what's more, high quality and automation have become its inexorable developing trend.This paper expounded the cutting theory, indicated difficult problems and keys on its development, according to the Mechatronics Principle, the analyzing and designing to the entirety > machine frame and the controlling system made the source梔istributing effective and the machine梕lectricity reasonable combining. The design procedure of the late-model cutting machine is discussed and the work-part performance is analyzed in this paper. To the machine system , CAD technology brought about auto-drawing, which improved the designing precision and efficiency. As far as the controlling system is concerned, automatic control to the cutting process is achieved to with the single-chip microprocessor, which meanwhile realized the low cost and high automation.The cutting machine belongs to grinding wheel cutting mode, it brought crosswise and vertical cutting ability to full play by suitable means. The machine adopted firstly omnibearing cooling system and closed cutting pattern, themeasures improved the sampling quality, enhanced the environmental protection and the operation safety; the paper advanced a kind of single-chip microprocessor system, it can not only accomplish the fundamental function, but also invent a new type of intelligent controlling system with Fuzzy Algorithm, which qualified the sampling quality. Experiments indicated that the Metallographic Sample Cutting Machine with reliable performance and unique designing fashion can operate without supervision , it reduced the labor intensity and raise the working efficiency, importantly, it accelerated the development of the metallographic as well as possessed highly application and dissemination.
