Rationale
The students of Mechanical Engineering branch are basically concerned with manufacturing various machine components in shops as per given drawing. Today the industrial processing and manufacturing techniques have become complex and complicated and their control is very much difficult by human judgment only. Therefore, the exact and precise measurements are the basic need of the industries. This course of Metrology & Instrumentation, therefore, provides required knowledge and skills and creates self confidence in students so that they can work on shop floor independently for accurate and precise measurements and manufacturing.
Course Outcome
The theory should be taught and practical should be carried out in such a manner that students are able to acquire different learning out comes in cognitive, psychomotor and affective domain to demonstrate following course outcomes.

i. Measure the given mechanical elements and assemblies using linear and angular analog /digital measuring instruments.
ii. Check geometrical accuracy of given application.
iii. Explain surface roughness checking instruments.
iv. Measure and derive important dimensions of various thread forms and gears.
v. Select and use non destructive testing methods.
vi. Check the dimensions using the gauges.
vii. Select and measure variables using appropriate sensors and transducers.
