6. Instruments for measuring capacity

The accuracy of the probe during scanning is generally several tens of micrometers, but this accuracy is generally not achieved for the measurement of well-known shapes as well as when the size of the part greatly exceeds the radius of the feeler ball because of the algorithms used for the sharp radius of correction stylets.

The presentation of the fuzzy logic algorithm has been introduced (see Figure 6); this logic affects one or more steps of the algorithm to try to increase its performance including accuracy and speed, and there are several variables. Some of these variables expand, and the abbreviation of the corresponding iterative point asserts that it would be a good response to the algorithm. To make an algorithm choice, there are several criteria that must be checked:

For example, spline profiles that do not compose a part of a geometric primitive known as (circle, sphere, cone, torus, etc.), they present particular difficulties to establish the method of the normal vector. Left surfaces are now very common (car, bodies, consumer products of ergonomic shapes, turbine blades, etc.).

In addition, small features become commonplace and, although measurements are made by digitization, the correction can result in the introduction of unacceptable errors [16–18].
