Pragmatic approach for estimating measurement uncertainties or the capability of CMM1S NC2

In three-dimensional metrology. Three-dimensional measuring means the means have been widely multiplied in recent years, in metrology laboratories, in production workshops, with the evolution of technology in general, the software associated with these machines are multiplied and allow to obtain the results of measurements with different methods. In this paper we carried out a series of measurements of ten (10) identical parts on a numerically controlled three dimensional measuring machine. To do this we carry out computer-aided design, three-dimensional of the type of parts, in three-dimensional design software, for the manufacture of parts subject to experimentation. The least-squares method is applied for the evaluation of the geometrical specifications of the parts. A measurement repeatability procedure was carried out in order to overcome the influences of the operator in the measurement results. We define the parameters allowing to estimating the uncertainties of measurements or of the capacity to measure numerically controlled three-dimensional machine. After several studies and experiments, we have found it is important to estimate the capability of its three-dimensional digital control means. Our article series up a pragmatic approach to estimating the uncertainties of measurement results or the numerically controlled three dimensional machine-to-machine capability. In a simple tool for three dimensional controllers. From the results obtained from the software associated with the three-dimensional measuring machine. The approach makes it possible to estimate the uncertainties or the capability of numerically controlled three-dimensional measuring machines.
