OBJECTIVES OF METROLOGY AND MEASUREMENTS
From the preceding discussions, we know that accuracy of measurement is very important for the production of a quality product, and hence it is imperative to mention here that the basic objective of any measurement system is to provide the required accuracy at minimum cost. In addition, metrology is an integral part of modern engineering industry consisting of various departments, namely design, manufacturing, assembly, research and development, and engineering departments.
The objectives of metrology and measurements include the following:
1. To ascertain that the newly developed components are comprehensively evaluated and designed within the process, and that facilities possessing measuring capabilities are available in the plant.
2. To ensure uniformity of measurements.
3. To carry out process capability studies to achieve better component tolerances.
4. To assess the adequacy of measuring instrument capabilities to carry out their respective measurements.
5. To ensure cost-effective inspection and optimal use of available facilities.
6. To adopt quality control techniques to minimize scrap rate and rework.
7. To establish inspection procedures from the design stage itself, so that the measuring methods are standardized.
8. To calibrate measuring instruments regularly in order to maintain accuracy in measurement.
9. To resolve the measurement problems that might arise in the shop floor.
10. To design gauges and special fixtures required to carry out inspection.
11. To investigate and eliminate different sources of measuring errors.
