In general, with current computer system, not only it is too difficult to create geometry model with many holes, but it is too difficult to analyze FE-model. In this research, to solve these problems, I used the techniques of global-local analysis and equivalent property analysis. To my satisfaction, I obtained good results. And, these techniques were helpful to solve similar these problems and obtain accurate results.

Recently, environmental pollution has become a significant problem in industry and many researches have been investigated in order to preserve the environment. Environmentally conscious machining and technology have more and more important position in machining process. In the milling process. the cutting fluid has greatly bad influence on the environment.<br/> In this study, the machinability such as tool wear, surface roughness and surface profile was investigated in the machining of blade parts(12Cr steel) using the cutting fluid, compressed cold air and oil mist etc. also, the productivity and the surface topography was improved by using new end-mill tool considering tool material and shape.

In industrially advanced countries, environmentally conscious machining was eagerly studied because of ecological and economical reasons. As the environmental regulations become stricter, new machining technologies which take environmental aspects into consideration are being developed Industry and research institutions established applications for dry, semi-dry, oil-mist and compressed cold air machining. This paper investigates the performance of new compressed cold air system for environmentally conscious machining and evaluates machinability of dry and new compressed cold air machining. A series of tests are carried out using measuring eqipments under dry and compressed cold air machining.
