The zCat direct computer control coordinate measure machine, or DCC CMM, is designed to be smaller and portable compared with traditional CMM devices. It has been in the making for more than four decades. The zCat traces its origins to Homer Eaton inventing the Romer Arm in 1974. The arm was a way to measure large objects, such as aircraft, without taking them to a measuring device. After finishing it, “I immediately realized the advantages that a motorized and computer-controlled version of it would offer and I went to work on it,” Eaton said. The technology, however, wasn’t yet in place to turn those ideas into reality. Now, in the 21st century, Eaton’s idea has taken the form of the zCat CMM machines produced by Fowler High Precision.
