Abstract

The mechanism and process of laser shock forming metal sheet is analyzed, which requires laser beam irradiating vertical to the surface of metal sheet. The metal sheet surface becomes complex after rough shocking and how to acquire normal vector of the complex surface is researched. Intelligent sensor of high resolution and numerical control system is adopted to configure a simple three-coordinate measurement system. The three-dimension information of the shocking point and its adjacent points is acquired through calculation and measurement. The normal vector of shocking point is estimated according to micro tangent plane. Two groups of data are measured for accuracy improvement and measuring process is given, as well as error evaluation. The key problem of precision forming metal sheet under laser shock is solved.
