Abstract
The aim of this article is to analyze the measurement procedures for part inspection with metrology software using scanners in a non-controlled environment, and to demonstrate the effect of different ?ltering factors on geometric dimensioning and tolerancing (GD&T) analysis. The effects of GD&T ?t methods (i.e., least- squares vs. mating-envelope) are also investigated, because their behaviors vary greatly with noise levels. An experimental plan based on the design of experiments (DOE) methodology is applied to determine factors affecting the variability in GD&T analysis. Experimental test cases combining these factors are discussed, and best practices are accordingly proposed.
