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 Diameter of Wire used Sharp V?
Diameter of Wire used Sharp V calculator uses Wire Diameter = (Micrometer Reading-Pitch Diameter+0.86603*Screw Pitch)/3 to calculate the Wire Diameter, Diameter of Wire used Sharp V formula refers to the size of the precision wires utilized in the three-wire method to measure the pitch diameter of screw threads, particularly metric threads. These wires are placed in the V-shaped groove of the screw thread and the measurement is taken using a micrometer. The diameter of these wires is crucial because it ensures accurate contact with the thread flanks, providing a precise measurement of the pitch diameter. Wire Diameter is denoted by G symbol.
