UNIT I CONCEPT OF MEASUREMENT
General concept – Generalized measurement system-Units and standards-measuring instruments: sensitivity, stability, range, accuracy and precision-static and dynamic responserepeatability systematic and random errors-correction, calibration – Introduction to Dimensional and Geometric Tolerancing – interchangeability.
UNIT II LINEAR AND ANGULAR MEASUREMENT
Definition of metrology-Linear measuring instruments: Vernier, micrometer, Slip gauges and Classification, – Tool Makers Microscope – interferometry, optical flats, – Comparators: limit gauges Mechanical, pneumatic and electrical comparators, applications. Angular measurements: – Sine bar, Sine center, bevel protractor and angle Decker.
UNIT III FORM MEASUREMENT
Measurement of screw threads: Thread gauges, floating carriage micrometer measurement of gear tooth thickness: constant chord and base tangent Method-Gleason gear testing machine – radius measurements-surface finish: equipment and parameters, straightness, flatness and roundness measurements.
UNIT IV LASER AND ADVANCES IN METROLOGY
Precision instruments based on Laser-Principles- laser interferometer-application in measurements and machine tool metrology- Coordinate measuring machine (CMM): need, construction, types, applications – computer aided inspection- Tool Makers Microscope- Non contact and in-process inspection, Vision system.
