Question

Which of the following option is true about an analytical method of inspection of gears?

(a) Analytical method is widely used for industries

(b) This method is fast

(c) All individual elements of gear teeth are checked

(d) More accurate

I had been asked this question in an online interview.

Asked question is from Gear Measurement in section Measurement and Testing of Gears of Engineering Metrology

Answer 1

Right option is (c) All individual elements of gear teeth are checked

The best explanation: Analytical method is slow and tedious and not of much use for industry. By analytical inspection of gears we mean that all the individual elements of the gear teeth are checked. The discrete error values of pitch, tooth profile etc can’t give a true overall assessment of the accuracy of a gear.
