Research Abstract

High speed machining is one of promising technologies that will yield high economical production and high quality of the machined elements. Moreover, it is expected as a technology which can finish the product without the processes of grinding or polishing. However, high speed machining may be effective only in some particular areas of machining. No strategy for exploring such areas has been proposed and found. Thus the performances of high speed machining should be effectively evaluated by the virtual machining with the aid of computer simulation, which has a potential for optimizing machining operations.
In this research the various types of modiling of machining with different tools and chip formations, which caused by different combinations of work materials and cutting conditions, were first developed for clarifying the machining phenomena using finite element methods with different formations and finite difference method. The chip formations considered are continuous, discontinuous and serrated. The types of tools are flat and grooved in two dimensional machining, while a single point tool and an endmill are considered in three dimensional cutting.
Next the virtual machining methods are applied to the optimization of tool geometry. In this application the influences of tool geometry on tool wear, tool breakage and chip control were clarified by using cutting temperature, stresses on the tool face, tool deformation, and chip deformation and breakage. Then the optimized tool geometry for given cutting conditions and the optimized cutting conditions for given tool geometry were determined. The integration of cutting condition monitoring and cutting operation planning through the virtual machining method was investigated.
