June 2021 Tip: Tapers

By

TAPERS:

Machinists often turn, plane, bore, and grind tapers on a variety of parts, therefore, it is important to be familiar with the common standard tapers—American National Standard, Brown and Sharpe, Morse, and milling-machine arbor and spindle. How to determine the taper per inch or percentage of taper from a sample piece of work is a common problem. A study of the data and the rules in this section will help you handle taper problems.

Taper Calculations:

A cylindrical taper is a piece of material that decreases in diameter in a cone shape. Proportions for tapers are often expressed as Taper per Foot (TPF), or Taper per Inch (TPI). Taper calculations are most often expressed in terms of the difference in diameter at the opposite ends of the taper and the length of the taper center axis.

Contact me if you would like for me to email the full PDF with all of the taper calculations to you. You may also download the Tapers PDF.
