It the feel is checked against gage blocks and then duplicated on a cylindrical part of the same size, the reading will very 0.02 mm or more. 4. But one division on the thimble is equal to to0.01 mm. It is interesting to see that as the angle of Eve is 60° the micrometer will measure a distance of 1.5d for a round piece of diameter’ It is simple to obtain from reading. Below shown the general arrangement of outside micrometer and it’s various parts. Hold workpiece which dimension to be measured between anvil and spindle as shown in Fig. In order to increase accuracy, the vernier principle also is applied to an outside micrometer. At this point, a reading is taken and this should read zero i.e., the thimble should coincide with the zero reading of the barrel. The bench micrometer principle makes use of a magnifying technique i.e., a gap of 0.01mm between the anvils is equivalent to a division width of the thimble of about 1mm. All graduations lines on the barrel (sleeve) should clearly engrave and for easy reading, the surfaces of thimble and barrel should have a dull finish and the graduation lines should be blackened. It allows the anvil to touch only one point on the object. Tip: If the half mm increment is showing on the primary scale, add 0.5mm to the total reading. The actual size (x) of the component will be x = M + (R2 – R1) which assumes that the standard is smaller than the component. Large diameter thimble permits the greater number of divisions around the large circumference, thus promoting better accuracy. micrometer detail caliper - micrometer … The main scale reading is 17. The micrometer is available in various sizes and ranges, and the corresponding micrometer should be selected depending upon the size of the workpiece. Then the thimble is turned till the measuring tip touches the part and the final movement is provided by ratchet so that uniform measuring pressure is applied. This device is inexpensive, lightweight, compact, and relatively rugged. Hence one division on a vernier scale is equal to9/10thatofthimble.
