Tolerancing & Templates
Tolerancing
Tolerance is the acceptable amount of deviation from the perfect, or nominal,
values of a part. For example, a bi-directional tolerance states how much (+ or
-) the location of a feature may deviate from its nominal location. Use the
tolerancing function to calculate positions, orientations, and bonuses to keep
tolerancing simple and manageable. It is not even necessary to thoroughly
understand tolerancing to successfully use it with the QC-5000.
Tolerance Toolbar
Use the tolerance toolbar to activate any of the 12 tolerance functions supported
by the QC-5000.
NOTE
Tolerance is feature dependent. This means that only certain
tolerance functions apply to certain features. For example, a
cylindricity tolerance cannot be performed on a point.
