DESCRIPTION This study-unit introduces the students to the science of measurement and to gauging and measurement applications.

Study-unit Content:

- Measurement and gauging. Use and care of various measuring and gauging instruments. Angular and taper measurement.
- Use of sinebar, precision levels, and angle gauges. The principle of the Angle Dekkor and autocollimator. The rotary table and dividing head. Precision polygon.
- Use of telescopic and hole gauges. Flatness, straightness and roundness measurement.
- Design and use of limit gauges and comparators.
- General inspection equipment - The reference surface, surface table and surface plates. Toolmakers’ flat.
- Straight edges. Mean true plane of a surface plate. Right angle and box angle plate. Engineers’ square. Engineers’ parallel. Vee and ‘B’ blocks. Use of calibrated balls, rollers and pins. Taper parallel.
- Use of optics in Engineering Metrology.
- Surface roughness measurements.
- Coordinate measuring machines (CMM).

Study-unit Aims:

- To introduce students to the science of engineering measurement.
- To enable the student to learn methods and techniques used in industry to measure and inspect various dimensions.
- To enable the future engineer to suggest and analyse measurement procedures and reports.
