The final stages in the process of surface generation are often the most critical in determining product quality. Ideally the end point in the generation of surface shape or form should be reached at the same time as the desired quality of texture, roughness or polish. In practice, however, this situation is difficult to achieve because although form can usually be measured objectively, for example by the use of an interferometer, there is as yet no non-contacting means for measuring roughness and flaws post-process on-machine.
