Taper per foot formula
WebTaper Per Foot TPF = = [ (D - d) /L] x 12 or = TPI x 12 Included Angle of Taper = = 2 x ArcTan (TPF/24) or = 2 x (Angle to center line) Angle to Center line of Taper = = ArcTan (TPF/24) Referring to The Machinist's Handbook, what is the minimum pitch diameter for an external thread 7/16-14 UNC - 2A? A) 0.3862 inches B) 0.3909 inches C) 0.385 inches The taper angle is given by the equation: \qquad \theta = \tan^ {-1} (\mathrm {TPI}/2) θ = tan−1(TPI/2) Tapered workpiece Tapers can be specified using three parameters: Major diameter; Minor diameter; and Taper length. A typical taper can be specified using the above three dimensions.
