Radius measurement Surface finish measurement Straightness measurement Flatness measurement Roundness measurement. General concept Generalised measurement system: Measurement is a comparison of a given quantity with one of its predetermined standard values opted as a unit. There are two important requirements of the measurement:. Example: Weight of a substance is measured directly using a physical balance. To ensure that the part to be measured conforms to the established standard. To meet the interchangeability of manufacture. To provide customer satisfaction by ensuring that no faulty product reaches the customers.

Slideway Cross-Section Figure The width, depth, angles, and other dimensions must be produced and measured accurately for the machine tool to function as expected. Figure We arrive at the last measurement as follows: First note that the two lowest scales pertain to the inch units. We next note that the 0 zero mark on the lower scale has passed the 1-in.

Metrology is the science of measurement. This led to the creation of the decimal-based metric system in , establishing a set of standards for other types of measurements. Several other countries adopted the metric system between and ; to ensure conformity between the countries, the Bureau International des Poids et Mesures BIPM was established by the Metre Convention. Metrology is divided into three basic overlapping activities. These overlapping activities are used in varying degrees by the three basic sub-fields of Metrology. In each country, a national measurement system NMS exists as a network of laboratories, calibration facilities and accreditation bodies which implement and maintain its metrology infrastructure.
