People are in dire need of knowing whether the workpiece is satisfactory after laser forming while using the technology of laser forming with thermal stress. In order to solve the difficult problem of how to evaluate the quality of laser forming with thermal stress, surface quality evaluating indexes have been studied firstly; surface defects, surface roughness and surface association mechanical property (such as surface hardness, surface constitution, surface residual stress) are considered as primary measuring indexes of laser forming quality; the internal quality of laser forming is rested with the quality of forming area. Surface defects and their methods of calibration, surface roughness and its method of measurement, surface association mechanical property and its methods of measurement are introduced respectively. In the meantime, how to establish the quality evaluating system of laser induced thermal stress forming work pieces has been discussed, the work should be carried out after conforming to evaluation system, evaluation indexes and evaluation criterion.
