Pitch diameter from measurement over wires method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pitch Diameter = Micrometer Reading+0.866*Screw Pitch-Diameter of Wire Two Wire Method
D = M+0.866*P-G_o
This formula uses 4 Variables

Variables Used

Pitch Diameter - (Measured in Meter) - Pitch Diameter is the diameter of the basic cylindrical shape on which threads are created.
Micrometer Reading - (Measured in Meter) - Micrometer Reading is the reading of an instrument which can measure thickness of very small objects.
Screw Pitch - (Measured in Meter) - Screw Pitch is the distance between screw threads and is commonly used with inch sized products and specified as threads per inch.
Diameter of Wire Two Wire Method - (Measured in Meter) - The Diameter of Wire Two Wire Method is the diameter of the wire in thread measurements.

STEP 1: Convert Input(s) to Base Unit

Micrometer Reading: 8.2 Millimeter --> 0.0082 Meter (Check conversion here)
Screw Pitch: 3 Millimeter --> 0.003 Meter (Check conversion here)
Diameter of Wire Two Wire Method: 3.81 Millimeter --> 0.00381 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = M+0.866*P-G_o --> 0.0082+0.866*0.003-0.00381

Evaluating ... ...

D = 0.006988

STEP 3: Convert Result to Output's Unit

0.006988 Meter -->6.988 Millimeter (Check conversion here)

FINAL ANSWER

6.988 Millimeter <-- Pitch Diameter

(Calculation completed in 00.020 seconds)

How measurement over wires method is used to measure screw dimensions?

Measurement over wires is a method used to measure precision threads using the wires. Small hardened steel wires are of a precision size and accurately ground are used for this. Two wires are placed over the thread grooves in the opposed directions of the thread. Then the size is measured using a micrometre with the spindle and anvil touching the wire surface. Then the pitch diameter is calculated by formula given here.

How to Calculate Pitch diameter from measurement over wires method?

Pitch diameter from measurement over wires method calculator uses Pitch Diameter = Micrometer Reading+0.866*Screw Pitch-Diameter of Wire Two Wire Method to calculate the Pitch Diameter, The Pitch Diameter from Measurement over Wires Method formula is defined as the simple effective diameter of the screw thread, approximately halfway between the major and minor diameters. Pitch Diameter is denoted by D symbol.

How to calculate Pitch diameter from measurement over wires method using this online calculator? To use this online calculator for Pitch diameter from measurement over wires method, enter Micrometer Reading (M), Screw Pitch (P) & Diameter of Wire Two Wire Method (G_o) and hit the calculate button. Here is how the Pitch diameter from measurement over wires method calculation can be explained with given input values -> 6988 = 0.0082+0.866*0.003-0.00381.
