In cutting using rotary cutting tool, it is expectable to become low friction since cutting fluid can be supplied near the cutting point. The machining tests of Aluminum alloy using a rotary cutting tool were carried out. As a result, when the velocity ratio is very large, the cutting force Fx and Fy is nearly zero. However, Fz is a steady value when a velocity ratio is more than 20. And the coefficient of friction μ become small as the velocity ratio is large. The coefficient of friction μinfluences the angle and the depth of a texture which were formed on the rake face. The effects of a texture differ in the lubricous state.
