Gaging Success
CMMs and other multifunctional metrology devices are becoming faster and more sophisticated, but top-quality gages and measuring tools still have an important place As coordinate measuring machines (CMMs), vision systems, and ultra-fast probing heads gain market share, it might seem that traditional measuring tools such as bore gages and dial calipers should be approaching retirement. After all, the vernier caliper has been around since 1631, when French mathematician Pierre Vernier realized that using two overlapping scales—one fixed, the other sliding—would bring greater precision to his surveying measurements. The micrometer came along a few years later, after astronomer William Gascoigne developed a vernier screw for use in the telescope. Granted, the… Read More »Gaging Success
