What is the use of Three wire method ?
The accurate measurement of thread pitch diameter, which may be perfect as to form and lead, presents certain difficulties which result in some uncertainty as to its true value. The adoption of a standard uniform practice in making such measurements is, therefore, desirable in order to reduce such uncertainty of measurement to a minimum. The “three-wire method” of measuring thread pitch diameter, has been found to be the most generally satisfactory method when properly carried out, and is recommended for universal use in the direct measurement of thread plug and thread setting plug gauges.
How to Calculate Pitch diameter sharp v?
Pitch diameter sharp v calculator uses Pitch Diameter Sharp-v Thread = Micrometer Reading Sharp-v Thread-3*Wire Diameter of Sharp-v Thread+0.86603*Screw Pitch of Sharp-v Thread to calculate the Pitch Diameter Sharp-v Thread, The Pitch diameter sharp v formula is defined as the diameter where the thread thickness is equal to the space between the threads. Pitch Diameter Sharp-v Thread is denoted by Ds symbol.
