This paper presents a novel algorithm for planning a five-axis inspection path for arbitrary freeform surfaces. By converting the inspection path planning problem into a set-covering problem, the algorithm generates a near-minimum set of inspection paths that satisfy necessary constraints. Both computer simulation and physical inspection experiments confirm the effectiveness and advantages of the proposed method.
Freeform surface inspection is vital in manufacturing-related processes, and the newly emerged five-axis continuous sweep scanning technology offers to be a powerful means for accurate inspection of freeform surfaces. However, at present, for an arbitrary freeform surface, it still heavily depends on human intervention in planning an interference-free sweep scanning path, wherein typically the surface is simply partitioned into several subregions and sweep scanning paths are then individually planned for each subregion. In this paper, we present a novel and practical algorithm for automatically planning an efficient five-axis inspection path for an arbitrary freeform surface. The strategy is based on the idea of converting the inspection path planning problem into a set-covering problem, whose solution then gives out a near-minimum set of inspection paths for the freeform surface while subject to necessary constraints such as sampling resolution, collision-free, and others. Both computer simulation and physical inspection experiments of the proposed method have been conducted, and the results give a preliminary confirmation on the effectiveness and advantages of the proposed method.
