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

  • 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.
  • Measurement of surface finish by a Talysurf instrument.
  • Measurement of micro feature of a product (eg. Thread of a bolt or saw etc.) in a profile projector.
  • Determination of natural cooling characteristics of a heated object by using a thermocouple.
  • Measurement of air velocity across an air duct using anemometer.
