state the principale of screw gauge
Answers
- Working Principle Micrometer Screw gauge works on the simple principle of converting small distances into larger ones by measuring the rotation of the screw. This “screw” principle facilitates reading of smaller distances on a scale after amplifying them.To simply it further, let's take a normal screw with threads.
Answer:
For precise measurement of spherical or a cylindrical object, a screw gauge is the best instrument. An extremely fine-tuned screw gauge can be a bit difficult for untrained hands to use. This article’s objective is to make anyone and everyone aware of the basics of handling a screw gauge.
Screw Gauge Measurement Using the Micrometer
Screw gauge
Get acquainted with the structure of a Screw Gauge: Some sections are movable while others are stationary such as Sleeve, Anvil, Spindle, Thimble Lock, Frame, Thimble, Ratchet Stop.
Before starting to measure clean the spindle and anvil: Take a paper or a clean cloth and place in the midst of spindle and the anvil. Tighten the setup slightly until the paper or cloth is jammed and then pull it out, cleaning the setup in the process. This step is not necessary to do but helps in getting an accurate measurement as the preciseness is indispensable.
Place the object in between the spindle and anvil: Place the object carefully in between the anvil and the spindle. The anvil is stationary in nature, thus place the object against it. The object should be placed properly so that it does not move while taking the measurements......
