Rationale:

Metrology is the science of measurement, Diploma holders in this course are responsible for ensuring process and quality control by making measurements and carrying out inspection of various parameters. For this purpose, knowledge and skills about various measuring instruments are required. The aim of this subject is to develop knowledge and skills regarding various measuring instruments amongst the students.

Learning Outcomes:

After undergoing the subject, students will be able to :

• use verniercalliper, micrometer, Height gauge for linear internal and external measurement.
• use bore gauge, radius gauge, taper gauge, plug gauge, ring gauge, snap gauge for measurements.
• use bevel protector, sine bar, slip gauge, dial indictor, angle deckor, poppy dial for angular measurements.
• measure spur gear characteristics using gear tooth vernier, outside diameter over dovel pins.
• use tool makers microscope
• measure surface roughness parameters.
• use profile projector, auto collimeter, angle deckor.
• select and measure variables using electrical and electronics comparators and measuring instrument, sensors, transducers.
• select and use non destructive testing methods.
• explain the use of coordinate measuring machine.
• use the concept of limits, fits and tolerance in assembly of components
