METROLOGY AND MEASUREMENT LABoratory

OBJECTIVES

-To learn the scientific reasons of adoptions for different measuring processes of different types of components.

-To learn and prove that measurement is a language and essential for communication in the industries.

-To learn how different instruments are selected and used for different types of components.

-To learn different tools and techniques for statistical quality control.

-To develop the skill in using different methods and instruments, to ensure dimensional metrology and technological conditions for different critical shapes, couture, surface roughness etc.

LIST OF EXPERIMENTS

Taking measurements using following instruments :
Vernier height & depth gauge, (ii) Dial micrometer, (iii) Thread gauge, (iv) Radius gauge, (v) Filler gauge, (vi) Slip gauge.
Measurement of angle of a component using :
Vernier bevel protractor, (ii) Angle gauges , (iii) Sine-bar and slip gauges.
Checking / measuring parallelism, cylindricity and concentricity of components using dial indicator.
Measurement of a specific dimension for a lot of components, and prepare a histogram from the data obtained.
