3.1 Interpreting the Taylor principle
It was an English engineer, William Taylor, who filed a patent on September 30, 1905 for the control of screws by gages, who came up with the idea of using a system of Between and Not Between gages.
This system, known as the "Taylor principle", has been extended and applied to limit gauge verification of all smooth, splined, etc., fits.
This principle can be interpreted as follows:
The maximum material condition of an element of a part must be verified by a full-form Between gauge (figure 9a ), executed at the maximum material limit of this element.
The minimum material condition must be verified by a N'Entre Pas gauge executed at the minimum...
