“…Achieving accurate 3D models for full-scale areas, at least as large as the tire-surface contact area, in a short period of time constitutes a step forward on the use of 3D structural analysis techniques, such as those based on Finite Element Method (FEM) and on the description of surface irregularities and defects, such as texture and segregation [1,2]. In this context, the use of inverse engineering techniques (laser triangulation with laser line, among others) is more advantageous in relation to the methods used hitherto, because they allow collect a high density of data points, which combined with appropriate algorithms, allows extracting important information for road surface characterization [3][4][5][6][7][8].…”

a b s t r a c tLoads from vehicles alter the functional and structural characteristics of road pavements that directly affect the loss of resistance of the pavement and the users' comfort and safety. Those alterations require constant observation and analysis of an extensive area of road surface with high precision. For such it was developed a new scanning prototype machine capable of acquiring the 3D road surface data and characterize the road texture through two algorithms that allows calculate the Estimated Texture Depth (ETD) and Texture Profile Level (L) indicators. The experimental results obtained from nine road samples validate the developed algorithms for the texture analysis and showed good agreement between the scanning prototype equipment and the traditional Sand Patch Method.

Touch trigger probes are most widely used on coordinate measuring machines(CMM) and machine tools. Due to the tripod structure, pretravel of the probe varies when it triggers in different directions, which has been acknowledged as a key error source resulting in large measurement uncertainty. Return mechanism is one of the key factors affecting the probes' pretravel variation and repeatability. Currently, spring and magnet are two main return methods employed in trigger probes. Typical products are TP20 from RENISHAW with a spring return mechanism and T2 from TELES with a magnet return mechanism. Lobbing characteristics of those two kinds of touch trigger probes in the XY plane was studied analytically in this paper. Experiments were carried out on a high precision CMM to exam the mathematical model. Results show that theoretical model is in good consistent with the experiments; Both of the two kinds of probes have obvious lobbing characteristics especially when the stylus is relatively short. Long stylus leads to shrinkage PTV. Overall, TP20(spring return) has a better performance in experiments, but investigation from probe users show that T2(magnet return) stands longer due to its noncontact return mechanism.

“…The bias that characterizes the probe system is the pre-travel variation. Pre-travel is the distance traveled by the probe body from the point where the stylus tip makes contact with the measured surface until triggering occurs [7][8][9]. It has also been established that the pre-travel generally increases with the length of the stylus [7,10].…”
