Holographic interferometry is a useful technique for non-destructive inspection of deformation, displacement, and vibration for intelligent manufacturing systems. Especially, by using a photorefractive crystal as a recording material, real-time measurement is possible. We report on the application of interferometry for measuring mechanical processing error caused by the deformation of cutting tools. To achieve precise material processing and cutting using a lathe, microscopic deformation of cutting tools cannot be ignored. The deformation of tools is mainly due to the friction and stress, which cannot be avoided during processing. The advantage of this procedure is that the real-time measurement is feasible
