“…Indeed, it would reinforces recent technology of metrology, where the big accuracy exists when using the three dimensional measuring machine. In fact we sustained several authors even if this axis of measure procedure for example the works that is published by the article [1,[3][4][5][6][7], we can consider this work has a continuity of the precedent one.…”

“…In some difficult cases, new techniques based on neural networks could be applied to generate rules as explained. The paper [1] includes a brief discussion of presented fuzzy logic set up optimization with examples of the improved performance. Initially, in order to represent the value of these variables, we chose the simplest approach of using the bell function.…”

“…The proposed algorithm is dedicated to high definition measurement. Advantages of the algorithm are that we do not calculate the normal vector and we do not use a NURBS for smoothing (filtrating) of the measured shape [1]. The method is based on the fuzzy logic algorithm, which is a well known method to approximate the ideal position that minimizes the sum of squared residual errors between the clearance and the model.…”

Abstract. Three dimensional coordinate metrology is a firmly established technique in industry. Scanning technology is now widely used in coordinate metrology and is increasingly used for the measurement of small features. This paper presents a new real shape approach to closest point inspection involutes curve of gear tooth by coordinate measuring machinery (CMM). This method aims to select the most likely contact point for each successive arc by applying geometrical criteria and a fuzzy logic estimator. This method is particularly, but not exclusively, suitable for the metrology of features with small radii as well as metrological discontinuities. It does not require obtaining the normal vector traditionally used for probe tip correction. Elapsed time is 144.09 s. Tests have been done on limps of machine tool speed (pinion type cutter), which is highly applied in our country.

“…It has been shown that specimen surface roughness has also significant influence on the touch trigger probe pretravel variation independently on applied measuring force [2]. Another approach for stylus tip radius correction has been based on the use of the part CAD model using straight line measurement [3]. Some other researchers studied the influence of the actual configuration of the probe length and volume on the accessibility of inner features, such as slots and holes [5].…”

This paper aims at studying the effect of the dynamic errors on surface measurements using three different types of touch trigger probes attached to a bridge-type-CMM. Unforeseeable dynamic root errors of a ductile touch trigger probing system have been characterized theoretically and experimentally as well. The results were employed in validating a developed analytical twodimensional-model (2DM) of stylus tip to be developed to demonstrate the capability of such approaches of emphasizing the root error concept, and to evaluate the accuracy of the CMM measurements. A set of experiments was conducted; the results were analyzed in order to investigate the effect of the dynamic root errors in the light of probe scanning speed at different stylus tip radii. Variations in the mass and geometry of the stylus have their consequent effects on its inherent intrinsic dynamic characteristics that in turn would cause relevant systematic root errors in the resulting measurements. 3D bore cylindrical surface form undulations were measured by employing a probe on the trajectory of internal surface diameter for the standard reference test gauge ring. Regression analysis was applied on the results of measurement density distribution; uncertainty of measurement repeatability was then evaluated and graphically presented. The results were investigated and optimum strategic measurement parameters could thus have been derived to ensure foreseeable accurate and precise results.
