Metrology and Measurement is a subject that deals with the science of measurement and its application in various fields such as engineering, manufacturing, science, and technology. The syllabus for this subject generally covers the following topics:
- Introduction to Metrology: Definition and significance of metrology, systems of measurement, international system of units (SI).
- Linear and Angular Measurements: Measurement of length, gauge blocks, interferometry, optical methods, coordinate measuring machines (CMMs), angle measurement, goniometers, and autocollimators.
- Measurement of Force, Torque, and Pressure: Calibration of pressure gauges, measurement of force and torque, load cells, and dynamometers.
- Temperature and Humidity Measurements: Thermocouples, thermistors, resistance temperature detectors (RTDs), pyrometers, thermal imaging, psychrometry.
- Electrical and Electronic Measurements: Basic concepts of electrical measurements, instruments and methods for AC and DC measurements, measurement of resistance, inductance, capacitance, and power.
- Measurement of Time and Frequency: Standards of time and frequency, atomic clocks, quartz oscillators, frequency counters, and time interval analyzers.
- Measurement Errors and Uncertainty: Classification of errors, sources of errors, error analysis, propagation of errors, statistical analysis of data, measurement uncertainty.
- Metrology in Manufacturing: Measurement in machining, assembly, and inspection, tolerances and fits, geometric dimensioning and tolerancing (GD&T), and statistical process control (SPC).
- Metrology in Quality Control: Quality control methods, inspection techniques, acceptance sampling, quality assurance.
- Metrology in Engineering Design: Design for manufacture and assembly (DFMA), design for inspection, tolerancing, and metrology in product design.
Overall, the subject of Metrology and Measurement provides an essential foundation for understanding and implementing accurate measurement techniques in a wide range of industries and scientific fields.
