To avoid confusion, spell out. The letter 'R' as shown is used widely in drawings and is short for the word Radius. A committee that reviews some nonconforming materials which are submitted as potentially still usable/saleable (if the nonconformance does not hinder fit or function). Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 is one of the widely used standards. A nominal dimension for the stock material, such as. In most cases, the weld width (or diameter) is located to the left of the weld symbol (expressed here in inches), while its length is written to the right . Dimensioning a drawing also identifies the tolerance (or accuracy) required for each dimension. The latest revisions of Y14.5. With regard to surface roughness, it means that the heights of the individual microscopic peaks and valleys shall be averaged together via RMS to yield a measurement of roughness. For measurements of eccentricity and other deviations from nominal geometry, For an explanation of "type" abbreviated as "TY", see the example given at, Other features share the same characteristic.
