本文报道了用假定的具有不同程度前角表面粗糙度的碳化钨立铣刀头研究表面粗糙度对涂层粘附力影响的结果。采用230 ~ 1500粒度的磨石对碳化钨尖端进行磨削，并在尖端涂覆TiAlN膜、CrSiN膜和TiSiN膜。在连续车削过程中，测量了前刀表面薄膜的附着状态、表面粗糙度和切削阻力。结果表明，在产生切削截止点时，在尖端脊线附近和远离尖端脊线的前刀表面部分，最佳磨削粗糙度是不同的。由此可以理解，在切削过程中，工作材料的切削特性和与切削截止点接触的前刀表面的表面积分别产生各自的影响。
The results of an investigation on the effects of surface roughness on adhesion to the coating using the assumed tungsten carbide end mill tip with various degrees of rake surface roughness are reported here. The grindstones with varying in grit between #230 and #1500 were used to grind tungsten carbide tips and then coated the tips with TiAlN film, CrSiN film, and TiSiN film. The state of adhesion on the films on the rake surface as well as the surface roughness and cutting resistance were measured in the continuous lathe turning. The results show that, in generating the cutting cutoff, the optimum grinding roughness differs between the near vicinity of the cutting-edge ridgeline and the part of the rake surface that is further away from the cutting-edge ridgeline. From that fact, it can be understood that the cutting characteristics of the work material and the surface area of the rake surface that is in contact with the cutting cutoff exert their respective influences during the cutting.
