Abstract:

In order to ensure the quenched quality of complicated surfaces, according to the factor that tool path planning of laser quenching for free-form surfaces is very important to the uniformity of surface hardness, based on analysis of characteristics of laser quenching, equal arc length method for determining the tool path of laser quenching for free-form surfaces was advanced. The optimized distance between tool paths of laser quenching was ascertained through experiments. In the end, an example computing the tool path using equal arc length method for B sample curve surface were applied to verify the feasibility of this method. 
