Assessment, measurement, precision and quality if you say these are objectives to prove something then here you must know that like for any other fact or concept the terms mentioned above also includes a science of its own. Usually depicted very often in branch we know as metrology.

But why do we need this science? Why that precision is so important? Then we ought to know that if dimensions of your machines used for very purposes in our daily lives would have not been made keeping precision in mind the benefits we are getting today would have not been possible. Those scientific experiments if were not measured on certain tools of scales the accuracy of the results would have been never attained and further results would have never been established to benefit us.

Metrology the branch is concerned with science of measurement. An accurate measurement involves several factors such as, length, time, temperature, electrical resistance and for these basic elements there are certain standards. The standards further help these elements to attain a specific value and hence the assessment provides with certain measurements ...
... which forms the very basis of origin of things.

The assessment incorporates:

Measurement methods

Measurement standards

Measurement instruments

Statutory requirements for measurement

Methods vary from things to things, standards are those reference values with which a set of certain other values are set, statutory requirements are permissible values which ascertain values and instruments are those which act as an aid to reach a value. Precision measuring machines are one such example of such instruments. These are now coming in latest technology to provide accuracy in values of measurements.

Even these precision measuring machines cannot be utilized fully if one very basic tool is missing and these are known as surface plates. These plates with their flat plane lay the foundation of geometric accuracy in dimensional measurement. It is almost impossible to do any precision measurement if they are not based on accurate tools. And flatness of these plates provides accuracy within close limits which is very important for precision measurements. This also brings the point that if surface plates are not accurate they may give inaccurate results for machines and so the substances with which they are formed play a crucial role.

Cast iron surface plates in this respect are being used since ages and benefit with their non modulating, rigid and unbreakable property. Square and round plates give more accurate results. These are manufactured with utmost concerns to their utility in precision measurements.
