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.
利用峰值高斯曲率测量激光微加工表面的研究
微加工表面的测量越来越受到人们的重视。通过对典型精密加工工艺的分析,研究了激光微加工表面峰的高斯曲率。激光微加工表面作为一种典型的微加工技术,其表面是由一个两层双曲面组成的,在鞍面上有许多连接峰,并且具有负高斯曲率。此外,凸峰数量增加,导致高斯曲率减小。最后,利用高斯曲率表征纹理、平面度和表面凸峰的形貌,具有较高的表征精度。完全满足了微加工表面质量高精度测量的要求。
