摘要： A coated cutting tool (10, 30) for chipforming machining of materials, as well as a method for making the same, wherein the coated cutting tool includes a substrate (34). The substrate has a rake surface (16) and a flank surface (14) wherein there is a cutting edge (18) at the intersection of the rake surface and the flank surface. There is a coating scheme (32) on at least a portion of one of the rake surface or the flank surface of the substrate. The coating scheme includes a top oxide interference film (48) that visually appears to be colored when viewed under white lighting formed by full or partial anodization of an anodizable layer (42).
