对不同硅含量的铝合金进行了一系列正交切削试验，研究了近干切削条件下切屑的形成过程及被切削材料与刀具前刀面的粘附情况。当用烧结金刚石工具切割时，无论硅含量的量如何，都没有观察到粘附。另一方面，当用硬质合金和DLC涂层刀具切削时，粘附量随着铝合金中硅含量的增加而增加。当前刀面上的名义摩擦系数为0.3或更小时，不形成粘附，而当名义摩擦系数为0.4或更大时，形成粘附。当用硬质合金刀具和DLC涂层刀具切削时，粘附量随着前角的增加而减少。
Series of orthogonal cutting tests of aluminum alloys with different amount of silicon content have been carried out to investigate the chip formation process and adhesion of the work material to the rake face of the cutting tool under near dry cutting conditions. No adhesion is observed when cut with the sintered diamond tool regardless of the amount of the silicon content. On the other hand, the amount of adhesion increases with an increase in the silicon content in the aluminum alloys when cut with the cemented carbide and DLC-coated tools. No adhesion is formed when the nominal coefficient of friction on the rake face is 0.3 or less, and adhesion is formed when the nominal coefficient of friction is 0.4 or more. The amount of adhesion decreases with an increase in the rake angle when cut with the cemented carbide tools and the DLC-coated tool.
