[ME 2014,Set-1]

Question 16:A taper hole is inspected using a CMM, with a probe of 2 mm diameter. At a height, Z=10 mm from the bottom, 5 points are touched and a diameter of circle (not compensated for probe size) is obtained as 20 mm. Similarly, a 40 mm diameter is obtained at a height Z= 40 mm.The smaller diameter (in mm) of hole at Z = 0 is

[ME 2006]

Question 18:Two slip gauges of 10 mm width measuring 1.000 mm and 1.002 mm are kept side by side in contact with each other lengthwise. An optical flat is kept resting on the slip gauges as shown in the figure. Mono-chromatic light of wavelength 0.0058928 mm is used in the inspection. The total number of straight fringes that can be observed on both slip gauges is​
