The Coordinate Measuring Machine first appeared in the early 60's and the Coordinate Measuring Machine (CMM) industry was immediately born. The earliest Machine was a 3D devices with a simple DRO displaying the XYZ position of the X Y Z Machine.

Ferranti Metrology started the UK CMM Industry and licensed their technology to Bendix Corporation in the U.S after a short period where Bendix acted as CMM Sales Agents in the US for the Ferranti CMM. Bendix CMM became the dominant CMM Supplier with its Cordax CMM during the 60's and 70' later becoming known as the Sheffield CMM or Sheffield Company. The Cordax CMM was primarily a Cantilever Style Manual CMM with Hard Probes migrating to Touch Probes from Renishaw as the technology became available. DCC CMMs from Cordax and Sheffield also became popular as computers entered the field of CMM Metrology." I$ p, [, @+ G8 Q; J# W

Ferranti计量公司开创了英国的坐标测量机工业,作为Ferranti计量公司的坐标测量机代理商,美国的邦迪克斯公司得到授权,开始生产坐标测量机。邦迪克斯坐标测量机处于六七十年代统治地位,并最终发展成为今天的谢菲尔德测量机公司。邦迪克斯坐标测量机最初只生产配置硬测头的手动悬臂测量机,慢慢演变成可配置雷尼绍触发测头。当计算机应用于测量机工业后,邦迪克斯公司和谢菲尔德公司开始生产DCC坐标测量机。) z1 g: e2 d7 P& {

Sheffield was the dominant name in the CMM Market with its Apollo RS CMM, Cordax CMM, Sheffield 1808 in Manual CMM and DCC CMM configurations. The latest Sheffield CMMs are the Discovery CMM and the Endeavor CMM. Sheffield became part of Giddings & Lewis in the late '80's and are now known as Sheffield Measurement. Its CMM-Software called Direct Inspect and Measure Max, are one of the most well known and its CMM Programming Language, is Sheffield FLB. CAD Path Software provides the CMM Programming capabilities using CAD data. Federal Products built CMM's for a few years and in addition marketed the Renault CMM. Today Brown & Sharpe (BNS) are the largest Coordinate Measuring Machine builder; Brown and Sharpe have acquired Leitz, and DEA in recent years in an effort to consolidate the CMM Industry. Brown and Sharp produce CMM-Products including the Xcel CMM, Microval CMM, Reflex CMM, Mistral CMM, Scirocco CMM, Global CMM, Gage 2000 CMM in addition to other Metrology Tools.
