Abstract

The measurement of the microprocessing surface is attracting more and more attention. By analyzing typical precision machining technology, it studies the Gaussian curvatures of the peaks to measure a laser microprocessing surface. Laser microprocessing surface as one typical microprocessing technology, it shows the the surface consists of one hyperboloid of two sheets with many connected peaks on the saddle surface and a negative Gaussian curvature. In addition, the number of convex peaks increases, which leads to the Gaussian curvature decreasing. Finally, it shows that the characterization accuracy is high using the Gaussian curvature, which can characterize the texture and flatness and the topography of the surface’s convex peaks. It completely satisfies the requirements for high precision of the measurement of microprocessing surface quality.
