Abstract

Inspection of a free-form surface using Coordinate Measuring machine (CMM) can be challenging, particularly if the surface has a lot of curvature. CMM sampling strategies are necessary for companies to examine free-form surfaces quickly and affordably. The inspection cost in coordinate metrology with a CMM is directly related to sample size. A sound sampling plan lowers the inspection cost and sample size. This paper proposes a partial-novel adaptive method of the Modified Translation Propagation Latin Hypercube Design (MTPLHD) algorithm combined with Gaussian Curvature Patch (GP). The robustness and effectiveness of the adaptive method are compared with the most widely used sampling strategy, equi-parametric sampling strategy.
