Pitch of screw acme threads Solution

STEP 0: Pre-Calculation Summary

Formula Used

Screw Pitch = (Pitch Diameter-Micrometer Reading+4.9939*Wire Diameter)/1.933357
P = (D-M+4.9939*G)/1.933357
This formula uses 4 Variables

Variables Used

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.
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.
Wire Diameter - (Measured in Meter) - Wire Diameter is the diameter of the wire in thread measurements.

STEP 1: Convert Input(s) to Base Unit

Pitch Diameter: 7 Millimeter --> 0.007 Meter (Check conversion here)
Micrometer Reading: 8.2 Millimeter --> 0.0082 Meter (Check conversion here)
Wire Diameter: 1.2 Millimeter --> 0.0012 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (D-M+4.9939*G)/1.933357 --> (0.007-0.0082+4.9939*0.0012)/1.933357

Evaluating ... ...

P = 0.00247894206812296

STEP 3: Convert Result to Output's Unit

0.00247894206812296 Meter -->2.47894206812296 Millimeter (Check conversion here)

FINAL ANSWER

2.47894206812296 ≈ 2.478942 Millimeter <-- Screw Pitch

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 of screw acme threads?

Pitch of screw acme threads calculator uses Screw Pitch = (Pitch Diameter-Micrometer Reading+4.9939*Wire Diameter)/1.933357 to calculate the Screw Pitch, The Pitch of screw acme threads formula is defined as the distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis of the thread. It is represented by the letter p. (p=1/n). Screw Pitch is denoted by P symbol.

How to calculate Pitch of screw acme threads using this online calculator? To use this online calculator for Pitch of screw acme threads, enter Pitch Diameter (D), Micrometer Reading (M) & Wire Diameter (G) and hit the calculate button. Here is how the Pitch of screw acme threads calculation can be explained with given input values -> 2478.942 = (0.007-0.0082+4.9939*0.0012)/1.933357.
