What type and sources of error while using the micrometer screw gauge?

Answer 1

sources of error in screw gauge

Answer 2

Oh, dude, when you're using a micrometer screw gauge, you could have errors from things like parallax, worn-out anvils, or just your shaky hands. Sources of error can also come from temperature changes messing with the measurements or maybe even aliens messing with your tools when you're not looking. Just kidding on that last one... or am I?

Answer 3

Oh honey, when using a micrometer screw gauge, you better watch out for those pesky human errors like parallax or improper zeroing. And don't forget about mechanical errors caused by worn-out anvils or dirty threads. Just keep your eyes sharp and your equipment clean, and you should be good to go, darling.

Answer 4

when using a micrometer its supplied with a ratchet mechanism to regulate the pressure applied this does not always work properly so it is necessary to develope a feel for the correct pressure to apply,

it is also needed to regularly calibrate the micro to known gauges and to do this in a temperature controlled enviroment,when used the component should be the same temperature as the measuring instrument,in calibration care should be taken to ensure the jaws of the instrument are parallel and square to the body,wear should also be taken into account on the points of the calipers and faces of micro anvils,the adjustments on the caliper slides need to be set so there is no play,all measuring instruments should be kept in the same enviroment as the components for a time before measuring is done to even out the temperature between them,hieght gauges should only be sharpened on the nose of the scribing tool never the bottom,the base should be checked for damage and the table it is used on

Answer 5

Types of errors when using a micrometer screw gauge may include zero error (incorrect zero point calibration), parallax error (viewing at an angle), and measurement pressure error (uneven pressure on the object being measured). Sources of errors can also include wear and tear of the gauge, improper handling, and variations in temperature affecting measurements. Regular calibration and proper handling can help minimize these errors.

Answer 6

two types of zero errors are possible in screw gauge,positive zero error and negative zero error.

Answer 7

Over tightening the spindle.
