True Positional Diameter Calculator

A manufacturing inspection aid for comparing positional tolerance diameters of any two co-ordinate tolerances. Use the sliders to select the actual Delta X & Y amount as measured or use the sliders to select an arbitrary figure for the Delta X and Delta Y to analyze the results of a hypothetical condition. The answer will appear to the left of "= True Pos. Dia.” Using either method provides an instant comparison of the specified True Position Tolerance Diameter.
