Recently, environmental pollution has become a significant problem in industry and many researchers have investigated in order to preserve the environment. Environmentally conscious machining and technology have more important position in machining process, because cutting fluid has bad influence on the environment in milling process. This research is the experimental study on high speed machining of aluminum alloys through environmentally conscious machining. In this study, the surface roughness and chip appearance was investigated in the machining of aluminum alloys by dry machining, using cutting fluid and oil mist.

Environmental factors have become important in manufacturing planning due to governmental regulations and a growing preference for "green" products. However, planning decisions must also consider traditional dimensions such as production rate and quality. In this study, technology related to basic dicision method of environmentally conscious machining considered economic view was dealed. And experiments of dry type machining excluded coolant and semi-dry type machining using minimum coolant were established for the comparison of conventional machining ouputs.ng ouputs.

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.

Environmentally conscious machining and technology have been taking more and more important position in machining process. Since cutting fluid has some impact on environment, many researches are being carried out to minimize the use of cutting fluid. It can be Increased the environmental pollution through not using coolant any more or minimizing it. In this study, the cooling effects of cutting methods using the compressed cold air, dry cutting and cutting fluid will investigate in the blade machining. In order to examine the characteristics of cutting and tool in the environmentally conscious machining, this work investigates experimentally the degree of tool wear, cutting force and characteristics of surface roughness in relation to machining conditions and cooling methods.

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. The cutting fluid has greatly bad influence on the environment in the milling process. This research is experimental study on high speed machining of aluminum alloys through environmentally conscious machining. In this study, the machinability surface roughness and chip appearance was investigated in the machining of aluminum alloys applied dry machining and using cutting fluid, oil mist.

The purposes of using cutting fluid during cutting have been cooling, lubricating, chip washing and anti-corroding. However, the present manufacturing industry restricts the use of cutting fluid because cutting fluid contains poisonous substances which are harmful to the human body. Therefore environmentally conscious machining and technology have more important position in machining process because cutting fluids have significant influence on the environment in milling process. In this study, environmentally conscious machining can be obtained by the way of selecting the optimum machinig conditon using the design of experiment. Cutting using oil-mist showed better cutting characteristics than dry, air and fluid cutting with respect to by cutting force, tool wear and surface roughness. Also, the optimum machining condition for cutting using oil-mist could be selected through Taguchi method.

This paper presents the experimental results to verify the environmental consciousness with economic balances due to cutting fluid behaviors, effectiveness in machining process. Even though cutting fluid improves the Productivity through the cooling, lubricating effects, its environmental impact is also increased according to the cutting fluid usage. The primary mechanism considered in this study is the spin-off motion of fluids away from rotating workpiece. In this study some parameters arc adopted to analyze the productivity(tool wear), environmental impact(mist diffusion rate). The results present talc criteria for the resonable cutting fluid usage quantitative1y to develop the environmentally conscious machining process.

This paper presents a methodology to analyze the cutting fluid effectiveness in mechanical and thermal terms simultaneously using finite element method and experimental work. Cutting fluid plays many roles in metal cutting process. Mechanically-thermally coupled effectiveness of cutting fluids affect to friction coefficient at tool-workpiece interface and cutting temperature and chip control, surface finish, tool wear and form accuracy. Through this study, it can be explained that the critical behavior of cutting fluids will be able to apply optimal environmentally conscious machining process.
