Effective Diameter Measuring
Micrometer (EDMM) is also commonly known as FCM or
Floating Carriage Micrometer. This instrument is used
for accurate measurement of 'Thread Plug Gauges'. Gauge
dimensions such as Outside diameter, Pitch diameter,
and Root diameter are measured with the help of this
instrument. All these dimensions have a vital role
in the thread plug gauges, since the accuracy and interchangeability
of the component depends on the gauges used. To reduce
the effect of slight errors in the micrometer screws
and measuring faces, this micrometer is basically used
as comparator.
