The Study On Mechanical Design Of The Automatic Precise Cutting Machine And Its Controlling System

The Automatic Precise Cutting Machine is mainly used to cut the metallographic sample and all kind of material, which make the machine widely used in metal, ceramics, mineral,rock,compound material,electronic component, automobile and aviation etc. The design and manufacture of Automatic Precise Cutting Machine is still blank in china,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 Automatic Precise 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-distributing effective and the machine-electricity 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 ajid vertical cutting ability to full play by suitable means. The machine adopted double deck spray cooling system and closed cutting pattern, the measures is effective and 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 controllingsystem with Fuzzy Algorithm, which qualified the sampling quality. Experiments indicated that the Automatic prise 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.
