Question

What precise movement does CMM have?

(a) Precise movement in x coordinate

(b) Precise movement in x and y coordinates

(c) Precise movement in y and z coordinates

(d) Precise movement in x, y and z coordinates

This question was posed to me in a job interview.

My doubt is from Coordinate Measuring Machines topic in chapter Machine Tool Metrology of Engineering Metrology

Answer 1

Correct option is (d) Precise movement in x, y and z coordinates

The explanation is: Co-ordinate measuring machines are useful for three dimensional measurements. These machines have precise movements in x,y and z coordinates which can be easily measured and controlled.
