The definition of the gauge (measurement bracket): - The gauge is a special inspection device for measuring and evaluating the dimensional quality of parts.
The parts are accurately mounted on the gage, and inspections of the parts, profiles, and edges of the parts are carried out by visual inspection or by means of measuring tools, calipers and inspection pins. Modern gages can take into account the function of the measuring stand at the same time when designing the structure. - The measuring bracket is an auxiliary bracket used for measuring parts using a coordinate measuring machine. All supporting surfaces (points) and positioning reference surfaces (points) must be milled according to the CAD data of the parts. Some special parts are also used for measuring brackets. Should have the function of some gages. 4.1.2 The inspection tool and measuring stand can reasonably measure the geometric parameters of the part based on the valid product drawings and CAD data. The CMM can be used to check and identify the inspection tool and the measuring stand.
