Question

The method used for determining the angle of internal dovetail for some measurements. Which of the following is suitable for this method?

(a) Angle of taper plug gauge

(b) Any round taper work which can be placed on a surface

(c) Any flat tapered work which can be placed on a surface

(d) Angle of taper ring gauge

I have been asked this question in class test.

This question is from Determine the Included Angle of an Internal Dovetail in chapter Miscellaneous Measurements (EM) of Engineering Metrology

Answer 1

Correct option is (d) Angle of taper ring gauge

To elaborate: This method is suitable to check angle of a plug gauge which is tapered and any round and flat tapered work which can be placed on a surface. Angle of taper ring gauge can be determined by the method of finding the angle of tapered hole by using balls.
