The indicator traditionally would be a dial indicator; today dial-type and digital indicators coexist. The earliest expansion of "TIR" was total indicated run-out and concerned cylindrical or tapered (conical) parts, where " run-out " (noun) refers to any imperfection of form that causes a rotating part such as a shaft to "run out" (verb), that ...
Typically run-out is measured using a dial indicator pressed against the rotating component while it is turned. Total indicated run-out (TIR) is a technician's term for the measured run-out of any rotating system, including all forms of run-out, at the measured point. [3]
total indicator reading; total indicated run-out: For measurements of eccentricity and other deviations from nominal geometry TOS: top of steel: TOL: tolerance, tolerancing: TSC: theoretical sharp corner(s) See discussion at SC and POI. TY: type: For an explanation of "type" abbreviated as "TY", see the example given at "CL" meaning "class ...
Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.
Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.

Jackson, who leads the league in total yards, completed 16 of 22 passes for 177 yards. He also had 17 rushing yards, including a 10-yard keeper off right end early in the second quarter to get the ...
Vibration problems generally result in noise, bad surface quality and sometimes tool breakage. The main sources are of two types: forced vibrations and self-generated vibrations. Forced vibrations are mainly generated by interrupted cutting (inherent to milling), runout, or vibrations from outside the machine.
