Ring gauge uncertainty analysis
A ring gauge, also called a correction ring gauge, is a ring with specific dimensions and properties used to correct the insufficiency of a measuring tool. Ring gauges are limit gauges for shafts, mainly used to measure shafts or other external dimensions with a tolerance level of 1T6 to 1T16. The ring gauge cannot inspect the parts and crankshafts machined on the positive center, and the scope of application is limited. Ring gauges can be divided into: smooth ring gauges, also called halo gauges, threaded ring gauges, parallel thread gauges, etc.; according to different uses and manufacturing standards, they can be divided into: standard ring gauge, SK standard ring gauge, German standard Ring gauges, pipe ring gauges, etc. According to the different manufacturing materials, there can also be ceramic ring gauges and metal ring gauges. Measurement uncertainty refers to the degree of uncertainty about the measurement results, which reflects the lack of understanding of the ...
