Abstract
In order to research effect on the cutting performance for aluminum alloy by mixing isopropyl alcohol (IPA) and water, the performance of IPA aqueous solution was compared with IPA and water by the sliding test, cooling test and cutting test. Consequently, it was found out that IPA aqueous solution provided the best cutting performance in the cutting fluids. The sliding test between aluminum alloys revealed that IPA aqueous solution has a function that suppresses the adhesion of aluminum alloy. It seems that the adhesion on the tool decreased by this function. The cooling test of heated test pieces showed that the cooling ability of IPA aqueous solution was higher than that of IPA. Because of high cooling ability, the chip in cutting with IPA aqueous solution mist might curl smaller than that in cutting with IPA mist.
