Generally, wet cutting which supplies a lot of cutting fluid is adopted as precision cutting of the aluminum alloy used abundantly at the parts for automobile. When near-dry cutting is used as this processing, it is easy to grow up a built-up edge, and guarantee of dimensional tolerance or surface roughness is difficult. So, in this study, it aimed at an elucidation of the generating mechanism of a built-up edge and development of the reduction method for precision cutting of an aluminum alloy. This pepper examined the basic examination result of the cutting performance, such as a cutting speed, cutting temperature, a coefficient of friction of a rake face, and surface roughness when using MQL (Minimum Qantity Lubrication) cutting of the A6061 (T6) material with a cemented carbide.
