The CNC Threading Calculator seen below can calculate the thread dimensions for Unified Threads, Metric Threads, Acme Threads and Metric Trapezoidal Threads. Threading Calculator is included in the Web Machinist Software Program Available Here

Above is the Web Machinist Program Main Screen.  Click Here for More Info

In the Threading Calculator (above) you simply click on the desired thread size and Threading Calculator outputs the Maximum Major Diameter, Minimum Major Diameter and Calculates the Nominal Major Diameter. Also output is the Maximum Pitch Diameter, Minimum Pitch Diameter and the Nominal Pitch Diameter. The Minor Diameter is also Output.  Besides the thread dimensions the threading feed rate in inches per revolution is also calculated for inch threads.  For thread measuring, the 3 wire thread measuring calculations are also calculated including Wire Size, Maximum Measurement over the wires, Minimum measurement over the wires and the Nominal measurement over the thread wires.  Threading Calculator is included in the Web Machinist Software Program Available Here
