Machine-set modular-fixturing system

A fixture building system to accurately position and fasten fixturing elements relative to an employed machine's coordinate reference frame, comprising:

• a fixed flat mounting surface, a locating tool, a machine tool spindle, and said fixturing elements, said locating tool is of tubular form having a tapered shank located at its upper portion, a cylindrical elongation concentrically extending from the base of said shank, and a cannular protrusion concentrically positioned and projecting from the base of said elongation, and said locating tool is carried in said machine tool spindle of said employed machine,an internal pilot diameter, an external pilot diameter, and an end-referencing surface forming said cannular protrusion are in perfect orientation to the coordinate reference frame of the employed machine, thus, by virtue of mating said internal pilot diameter, said external pilot diameter, or said end-referencing surface with said fixturing elements and fastening said fixturing element in this location, the said locating tool can position and fasten said fixturing element on said fixed flat mounting surface relative to said employed machine's coordinate reference frame.
