WebMar 29, 2024 · The formula for calculating T is: T = \frac {Di - Ds} {TI} Di is the major diameter, Ds is the minor diameter, and TI is the taper length. Now that you know what the formula is, let’s get into how to use it. The first thing you need to do is measure your taper length (L). You can either use a ruler or an online tape measure to do this. WebThe drawing ratio is roughly calculated as, DR = D b /D p. D b is the diameter of the blank and D p is the diameter of the punch. For shapes that are noncircular the maximum diameter is sometimes used, or occasionally drawing ratio is calculated using surface areas. The limit to the drawing ratio for an operation is usually 2 or under.
