でもない。2. Description of the Related Art Generally, a single blade tool such as a cutting tool is used for external turning (turning) in which a work is rotated, a tool is cut, and feed is performed in a vertical direction. However, since cutting with a single-edged tool is continuous cutting, there is a limit to the cutting speed in consideration of tool life. Therefore, it is needless to say that intermittent cutting using a multi-edged tool such as an end mill is better than using a single-edged tool such as a bite in consideration of the efficiency of cutting.
