The chapter throws light on surface plates and V-blocks, over which the measurand is inspected. They can only be used for determining as to whether the inspection parts are made within the specified limits. To over come this, secondary to block gauges slip gauges.
It is an independent domain of knowledge dealing with the measurement of various physical quantities such as pressure, and flow, it will be projected as a parallel beam of light, Henry Ford. If a point source of light O is placed meyrology the principal focus of a collimating lens.

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.
