Background
Measurement is the use of data to describe the observed phenomenon, i.e. to make a quantitative description of things, according to a certain law. The measurement is a quantitative process for non-quantitative real objects. In mechanical engineering, measurement refers to the process of understanding experimentally that a measured quantity is numerically compared with a standard quantity having a unit of measure to determine the ratio of the two. Mainly refers to geometric quantities including length, area, shape, elevation, angle, surface roughness, form and position errors and the like. Since the geometric quantities are characterized by a wide variety of shapes, their characteristics, definitions of parameters to be measured, and standards must be studied and known in order to perform the measurements. Which refers to the degree of coincidence of the measurement result with the true value. Since any measurement process always inevitably generates measurement errors, the large errors indicate that the measurement result is far away from the true value and the accuracy is low. Therefore, accuracy and error are two relative concepts. Any measurement is represented as an approximation due to measurement errors.
