| Chapter / Section | Core Topics & Concepts | | :--- | :--- | | | Definition of metrology, generalized measurement system, units and standards, sensitivity, readability, accuracy, precision, static and dynamic response, repeatability, systematic and random errors, correction, calibration, and interchangeability. | | 2. Linear & Angular Measurements | Detailed study of instruments for measuring length and angles. This includes discussions on rules, calipers, micrometers, vernier calipers, and height gauges for linear measurements, and bevel protractors, sine bars, angle gauges, and autocollimators for angular measurements. | | 3. Limits, Fits, Tolerances & Gauges | The principles of interchangeable manufacture, including the systems of limits, fits (clearance, interference, transition), and tolerances (unilateral, bilateral). It also covers the design and application of various gauges like plug, ring, snap, and adjustable gauges. | | 4. Comparators | The principles and construction of various comparators used for precise relative measurements. This includes mechanical comparators (like dial indicators, Johansson Mikrokator), optical comparators, electrical and electronic comparators, and pneumatic comparators. | | 5. Measurement of Surface Finish | The nature of surface texture, its importance in functional performance, and methods for its evaluation. It explains parameters like CLA (Ra), RMS (Rq), and concepts such as waviness, lay, and flaws. The use of stylus profilometers, Tomlinson surface meters, and comparison methods are also described. | | 6. Metrology of Threads & Gears | Dedicated chapters on the specialized measurement techniques for screw threads (effective diameter, pitch error, flank angle) and gear parameters (pitch, profile, runout) using various instruments and methods. | | 7. Interferometry & Optical Measurement | The use of light-wave interference for high-precision measurements. It covers the principles of interferometers (like Michelson, Twyman-Green, NPL) and their applications in measuring slip gauges, angles, and flatness. | | 8. Quality Control, Assurance & Management | In-depth coverage of modern quality practices including Statistical Quality Control (SQC) , Total Quality Management (TQM) , Quality Assurance (QA) , reliability analysis, and ISO series standards. | Since PDFs are static, watch videos of CMM
