For over 50 years, the benchmark for accuracy in measuring solid objects, whether machined, molded, die cast, welded or forged, was the coordinate measuring machine. Using a solid granite base table typically, along with a vertical, horizontal, gantry or bridge-mounted arm and touch probe, measurements would be taken and compared in blocks to an engineering file, first as 2D drawings and today as CAD files hosted in the cloud.
During the last two decades, however, a “new kid in town” has arrived on the scene, with power, size, point capability and price value that are rapidly leaving the CMM technology in the dust.
