Mechanical Measurements and Metrology (MMM) laboratory is used by UG Students for measurements of various dimensions and tolerances of many components, and the procedures taught in the lectures are put into practice and expanded through practical trainings. Engineering metrology deals with the applications of measurement science in manufacturing processes. It provides a means of assessing the suitability of measuring instruments, their calibration, and the quality control of manufactured components. 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 the basics of measurement, standards and systems of measurement, tolerances, measuring instruments, and their limitations.
The MMM lab is equipped with a number of sophisticated equipment’s, for calibration, and for dimension measurement experiments to measure angular, linear measurements and tolerances. Furthermore, calibration of micrometre, slide callipers and other similar gauges. Several optical instruments for measuring linear and angular dimensions. Calibration of pressure, temperature, torque, stain gauge and load cells. Additionally, thread measurement by optical means and compound micrometre with 1, 2, 3 wire methods. Mitutoyo Instrument for measurement of surface roughness of various components.
Scope of Metrology
- Establishing units of measurement and their standards such as their establishment, reproduction, conservation, dissemination and quality assurance
- Measurements methods, execution and estimation of their accuracy.
- Measuring Instruments- Properties examined from the point of view of their intended purpose
- Observers capabilities with reference to making instruments, eg: readings of instrument indications
- Design manufacturing and testing of gauges of all kinds
Mechanical measurements and Metrology Lab has various measurement and calibration equipment’s. The major measuring instruments available are Profile projector, Tool maker’s microscope, Floating carriage micrometer, Autocollimator, etc. The major calibration equipment’s are Sine bars with slip gauges, Thermocouple, Sine center, Strain gauge, Pressure gauge, etc.
