For more than 50 years, the benchmark for accuracy in measuring solid objects, whether machined, molded, die-cast, welded, or forged, was the coordinate measuring machine (CMM). Typically using a solid-granite base table, along with a vertical, horizontal, gantry, or bridge-mounted arm as well as a 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.
