Discussion on Inspection and Measurement: Concentricity, Coaxiality, and Uneven Thickness
Introduction to topics such as concentricity, coaxiality, and measurement methods! Discussion on inspection and measurement.
Concentricity and coaxiality are positional tolerances applied to related geometric shapes. Coaxiality refers to "the magnitude of deviation of the axis line that should be on the same straight line as the datum axis line from the datum axis line," while concentricity refers to "the magnitude of deviation of the center of another circular shape relative to the center of the datum circle in the case of planar shapes." Measurement methods for concentricity and coaxiality include roundness measuring machines, center support or V-block reading methods, and three-dimensional measuring machines. 【Contents】 ■ About concentricity and coaxiality 1) Definitions and illustrated examples 2) Tolerance zones (allowable ranges) 3) Measurement methods ■ Thickness measuring instruments *For detailed content of the article, please refer to the related links.
