screw gauge मीनिंग इन हिंदी

The position of the rod is determined by a micrometer screw gauge or spherometer.
It may be expressed in fractions of an inch or a whole number that corresponds to machine screw gauges.
For example, if the shaft of a lathe is angled slightly, the part will have errors in diameter far down the part . vernier caliper are not free from abbe error while screw gauge is free from abbe error.
A "'micrometer "'( ), sometimes known as a "'micrometer screw gauge "', is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades, along with other digital calipers.
