Flashcards in Chapter 5 Deck (13):
Linear or angular sizes of components specified on the part drawing.
Since it is nearly impossible and costly to make components to exact drawing dimensions, this is the limited variation allowed while maintaining proper functionality. Difference between the max and min limits
Define: Bilateral vs Unilateral Tolerance
Bilaterial: Variation allowed both ways (positive and negative).
Unilateral: Variation allowed one way
Procedure in which an unknown quantity is compared with a known standard
Degree in which the measured value agrees with the true value of the quantity of interest.
Degree of repeatability in the measurement process.
(or Gauging); Determines simply whether the part characteristic meets or does not meet the design specification.
Consists of two legs joined by a hinge to measure the length or width of an object.
Measuring device that consists of a spindle and C-shaped anvil.
Define: Nominal Surface
Representing the intended surface contour of the part.
Define: Surface Texture
On the exterior of a part, the surface topography that is generally not straight and sooth. The way in which the surface roughness, waviness, and flaws combine in patterns and directions are included in the surface texture.
Refers to the small, finely spaced deviations from the nominal surface that are determined by the material characteristics
