Development Of Web-Based Physical Simulation System For Ball-End Milling Process

In order to meet the requirement for the development of advanced manufacturing, the thesis deals with the ball-end milling in the virtual manufacturing technique by means of metal cutting theory and numerical analysis and computer technology, etc. Emphases are placed on the modeling and simulation of milling force, the milled surface generation mechanism and milled surface topography simulation method. The creative contributions may be summarized as follows:(1) In the aspect of modeling and simulation of milling force, based on an approach for describing the ball-end mill. Moreover, a three-dimensional ball-end milling force model based on dividing the work-piece and cutter is given.(2) In the aspect of milled surface generation theory and simulation for milled surface topography, the steps of three-dimensional topography simulation and corresponding examples are given. This algorithm can completely emulate the milling process. Finally, the milled surface finish is evaluated by means of RMS (Root Mean Square).(3) From the perspective of software engineering, feasibility and demand analyses of the web-base physical simulation system are performed. The framework of the software system is designed.(4) A Web-based ball-end milling system is developed with c sharp and asp.net programming language, which can be released by IIS and can also be perated in a long-distance fashion through a Web browser.The work in this thesis will lay a foundation for improving the virtual manufacturing theory and for developing the practical physical simulation system of milling process.
