Abstract
Cutting and friction experiments were conducted in various atmospheres to investigate the chemical effects on textured cutting tools. Cutting experiments of aluminum alloy indicated that the atmosphere affected the machinability of the textured tools; a larger effect was observed in the presence of gases, such as oxygen. A ball-on-disk friction apparatus was developed and used for the friction experiments. The texture effect was observed in the presence of oxygen－this trend was similar to that observed during the cutting experiments. These results indicate that oxidation is an important factor in determining the texture effect for machining aluminum alloy.
