通过铝合金正交切削试验，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性。当用烧结金刚石刀具切削铝合金时，在很宽的切削速度范围内几乎没有观察到工件材料的粘附。另一方面，在低切削速度下，当用碳化物和DLC涂层刀具切削时，观察到大量的工件材料粘附。随着切割速度的增加，粘附材料的量减少。前刀面上的平均摩擦系数几乎与粘附量成线性关系增加。采用EDS和AES等技术对粘接层的化学成分进行了分析。
Series of orthogonal cutting tests of aluminum alloys 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. Almost no adhesion of the work material was observed over a wide range of cutting speed tested when the aluminum alloy was cut with the sintered diamond cutting tool. On the other hand, large amount of adhesion of the work material was observed at low cutting speeds, when cut with the carbide and DLC-coated tools. The amount of the adhered material is reduced with an increase in the cutting speed. The average coefficient of friction on the rake face increases almost in linear relation with the amount of adhesion. The chemical components of the adhered layer were also analyzed by EDS and AES techniques.
