Vision System Versus Optical Comparator
Hexagon Manufacturing Intelligence asserts that the choice must consider the need for quantitative data, adequate resolution, environmental influences, traceability and provisions for automation. This article states the case for preferring an advanced vision system.
Making informed decisions about the choice of manufacturing technology requires giving careful consideration to the proponents of various competing alternatives. In this blog post, Hexagon Manufacturing Intelligence makes the case for an "all-in-one" vision system for part measurement versus the traditional optical comparator.
Although this article presents only one side of a many-sided discussion, it raises many of the issues that must be addressed and resolved when judging the relative merits of different approaches to part measurement. These include the need for quantitative data, adequate resolution, environmental influences, traceability and provisions for automation.
Despite the apparent bias against optical comparators, the article's perspective is a useful reference when evaluating other points of view on the most appropriate technology for part measurement.
