Question

Which one of the following instruments is widely used to check and calibrate geometric features of machine tools during their assembly?

Correct answer (C) Laser interferometer Solution Laser interferometers are high-precision instruments used for the calibration of machine tools. They are used to measure linear positioning accuracy, straightness, squareness, and angular errors (pitch, yaw, and roll) of machine tool axes during assembly and maintenance to ensure they meet specified geometric tolerances. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
