This is a report on the effects of cutting fluids, when various metallic materials are cut under orthogonal cutting at constant cutting speed. The effects of cutting fluids on cutting force, shear angle, etc. are investigated in the experiments. The kinds of cutting fluids used are water, water base and mineral oil base. The materials used in this experiment are carbon steel S10C, S15C, alloy steel SCM4,18-8 stainless steel (SUS27), cast iron (FC20) and 4-6 brass. The results obtained are as follows. 1. In such a low cutting speed as V=10m/min, cutting force and coefficient of friction decrease and shear angle increases by using the cutting fluids. The effect of the mineral oil base is greater than the water base. 2. The chip's type is often transformed to flow type from shear type by cutting fluids. 3. The effect of cutting fluids is greater in carbon steel than SUS27 with which the chips easier weld to the tool.
