Most shops set cutting speed and feed rate to hit a cycle time, check the dimensions, and call the part good. That leaves out a second layer of quality. Two parts can measure identically on a CMM and still perform differently in fatigue, sealing, or bearing service, because cutting heat and mechanical load leave a surface layer that dimensions never show. This article explains cutting speed surface integrity in plain terms, where feed rate pushes against it, and how we set bo
