Working Principle of Micrometer

Working Principle of Micrometer Points : Working Principle of Micrometer Pitch of an only start filament is defined as reserve as of one thread to the next consecutive thread or space travelled in nut in one whole revolution. Such when but a bolt have 24 threads per inch pitch will he 1/24” or else nut will move 1/24” in single revolution. If we create the nut m such a way that we preserve knows while it completes its 1/4th or 1/2 revolution, after that in 1/4th revolution of nut will move 114 of the space of pitch. Hence but a screw have 40 threads per Inch with its nut is evenly clear on its edge 25 like parts, next nut will travel in single total revolution 1/40 (pitch). Condition nut is enthused just one mark out of 25 marks after that It will travel 1/40 x 1/25 = 1/1000. But we convert 1/1000” to its decimal friction; it arrives to 0.001 and 1/40 approach to 0.025”. Thus it is extremely apparent that in one revolving the nut will go 0.025” and but It is enthused only one mark out of 25 symbols it will go 0.001”.
