Abstract: Topography of machined surface affects many of workpiece’s technical performance and function to a large degree in NC machining. Surface topography is one of the important research topics in surface science. Studies show that machined surface has some fractal characteristics such as randomness, disorder, self-similarity, self-affine and multiscale. Surface topography influences the mechanical properties, physical properties and the rate of finished products. Under certain situations, processing quality of optical elements is detected by detecting 3D micro topography of optical surface. The surface of the workpiece is observed by placing on the focal plane of optical microscope. If there are obvious defects on the workpiece surface, several focus images from this workpiece surface are acquired and processed by moving the optical microscope up and down several times. According to the result of image processing, we judge whether a workpiece is conformed to machining requirements. An image processing software based on MATLAB2012 language is proposed in this paper, which achieves processing and analysis for several focus images, then fitting the 3D surface topography.
