Abstract

The accuracy of cnc diamond machining processes in directly related to the form accuracy of the diamond cutting tools available. Consequently both diamond tool manufacturers and machining houses require methods for inspection. The accuracy of the cutting edge which is primarily generated by the intersection of a cylinder/cone with a flat, must be typically 75-150nm. Most test methods rely on observation of the final generated cutting edge via high powered microscope. Unfortunately this means that the diamond tool manufacturer cannot qualify the accuracy of the cylindrical/conical portion of the tool prior to lapping the final flat which generates the final cutting edge. Therefore errors can only be detected on a finished tool which may result in costly re-working.

金刚石加工单点成形刀具精度的干涉测量方法
cnc金刚石加工工艺的精度直接关系到金刚石刀具可用的形状精度。因此,金刚石工具制造商和加工车间都需要检查方法。切削刃的精度主要由圆柱体/锥体与平面的相交产生,通常必须在75-150nm之间。大多数测试方法依赖于通过高倍显微镜观察最终产生的切削刃。不幸的是,这意味着金刚石工具制造商不能在研磨最终平面(产生最终切削刃)之前确定工具的圆柱形/锥形部分的精度。因此,错误只能在成品工具上检测到,这可能导致昂贵的返工。
