Rationale

Measurement and Metrology deals with the application of science in Mechanical Engineering. It provides a means of assessing the suitability of measuring instruments, their calibration, and the quality control of manufactured products. A product that is not manufactured according to metrological specifications will have to incur heavy costs of comply with the specifications later. Any compromise in quality creates rapid negative sentiments in the market and cost of recovering the original market position would be quite high. Hence, an organization should strive towards a ZERO – DEFECT regime in order to survive in a highly competitive market, ensuring this aspect of manufacturing is the responsibility of a quality control engineer, who must be completely familiar with measurements and metrology and also their limitations.
By educating in the area of Measurement and Metrology students will enable to seek employment in engineering upon graduation while, at the same time, provide a firm foundation for the pursuit of graduate studies in engineering.

Course Outcome

After learning the course the students should be able to:

  1. Students will describe basic concepts of Metrology
  2. Students will select linear measuring instrument for measurement of various components
  3. Students select angular and taper measurement devices for measurement of various components
  4. Students will discriminate between various screws by measuring their dimensions
  5. Students will separate different gears through measurement of various dimensions of gears
  6. Students will discriminate capabilities of machining process by measuring surface finish of the component produced
  7. Students will evaluate quality of surface produced using various methods
  8. Students will describe basic concepts of mechanical measurement and errors in measurements.
  9. Students will select appropriate temperature measuring device for various applications
  10. Students will describe methods of measurement for various quantities like force, torque, power, displacement, velocity/seed and acceleration

Active Learning

Preparation of power-point slides, which include videos, animations, pictures, graphics for better understanding theory and practical work – The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should submit to GTU.
