INTRODUCTION

In order to produce components, manufacturer have to know whether the components meet the required dimensional and accuracy standards. Companies carrying out maintenance activities also need to know that the components they are working with, repairing or servicing are to the required size and accuracy. Measurement plays an important role in establishing these needs and supports other areas of assuring quality in the products produced. The process of finding out whether a product is accurate and to dimensional standards also needs to be done in an efficient and effective way. The provide a broad understanding of mechanical measurement that apply to a range of engineering applications such as measurement of temperature, velocity, flow, force, torque, strain, etc. Also, some tools for linear and angular measurements have been introduced.
