Learning to operate a profile projector is generally easier than training on the typical vision system. “To begin with, using a profile projector is extremely intuitive,” says Walter Wardzala, precision measuring instruments product manager for Mitutoyo. “When you see a part’s magnified shadow on the screen, you’ve got a direct connection to the workpiece--it’s obvious you are observing the actual part as opposed to the synthetic, processed images delivered by vision systems. Also, the display is very easy to see. The viewer stands upright in an ergonomic position parallel to the screen, which is large enough for a number of people to view at the same time, facilitating collaboration on measurement--and also making training that much easier.”
