Abstract In any industry, measurements have high importance, as the components that are manufactured should qualify within the specified tolerance limits. The coordinate measuring machines are accurate measuring instruments having flexibility to measure different geometries. CMM machines incorporate a probe that provides the information from which the location of the surface of the part under inspection, relative to the machine’s position. It has been observed that probes used in the CMM scanning machines are not producing the same results while measuring the real parts for different stylus lengths and measuring speeds. Various methodologies have been introduced to measure the uncertainty of the probe, which are tending to be time consuming. In this project, it is proposed to analyse different configurations, geometries and kinds of materials of the probe stylus to minimize the influence of the pre-travel errors of the probe system. This paper presents the method of evaluation of CMM probe uncertainty using finite element analysis. It has started initially by applying the minimum force of 0.1 N, on probe ball at equator position for various parameters like stylus length, stylus material, probe ball material and diameter. It is observed that, as the stylus length varies, the deflection also changes, respectively; the deflections can be represented in the form of a cubic spline which is a third-degree polynomial equation. These results can be used to analyse the uncertainty of the recorded results.
