基于刀-工适配动态系统物理原理的刀具基础大数据研究

The candidate submits the subject of sub-database of cutting tools which belongs to the subject groups of cutting database. It has a strong basic theory to establish the basic database of cutting tools from the view of suitability between cutting tools and work-piece; at the same time, because the cutting tools is not only the producing object of manufactured tools enterprise but also the using object of manufactured parts enterprise, it has a vast space. In this project, based on the dynamic, variable and bulk characteristics for datum of cutting physical principle, data mining methods of fundamentally physical datum will be studied to face the memory, calling and calculating for computer through cleaning, transferring, integrating and stipulating the datum, and the parameterization national standards which are composed of cutting tools sub-database will be constituted; based on the cloud computing, source and processing platforms of fundamentally physical datum for manufacturing and application of cutting tools will be built under at the internet environment, and constitutive models also will be established which is the key for the sub-database of cutting tools of cutting database, and a software system of fundamentally physical cutting database will be developed. The relationship model among datum, interaction between physic and information flows, criterion and constitutive of database, and mining of reliable information at the stage of big data in this study are one of the most important parts for intelligent manufacturing, and will promote the development of intelligent manufacturing technology of 2025 version industry in our country. Therefore, it has the great scientific and practical significance from the view of theory and engineer.
