“…From the above result, it is possible to conclude that fitting of measured points taken by laser tracker to surface of a model created in SolidWorks imported to SpatialAnalyzer software can be used as an inspection tool against a given specification. Various applications of a laser tracker have been discussed in [7][8][9]. e use of a laser tracker as instrumentation tool and inspection tool is in agreement with [4][5][6]11].…”

“…Literature reveals the use of laser tracker as a reference instrument for articulated arm coordinate measuring machines (AACMMs) verification processes by [7], as a calibration system for a coordinate measuring machine (CMM) by [8], as a metrology tool for aligning optical systems, including the use of mirrors and windows by [9], and as an instrumentation tool used to make large scale measurements within aerospace assembly by [6]. Laser tracker technology applications in the manufacturing sector include machining equipment and tool alignments, inspection of parts, complex assembly of components, equipment, machine and tool calibrations, and data collection of dimensional information for reverse engineering of components with three-dimensional information to complete solid parametric models that can be used to manufacture [4,10,11].…”

In this study, NACA0018 airfoil surface conformity test was conducted using API tracker3 in combination with SpatialAnalyzer (SA) and modeling software SolidWorks. Plaster of Paris is used as a plug making material and a woven-type fiberglass is used as mold and airfoil surface making material. For airfoil surface analysis, three-dimensional model of the airfoil surface was developed in SolidWorks software and imported in IGES file format to SpatialAnalyzer (SA) software. Then, measurements were taken from manufactured airfoil surface using laser tracker through surface scanning method. Surface conformity test was conducted through fitting of measured points to surface model imported from SolidWorks to SpatialAnalyzer (SA) software. The optimized fit summary result shows that the average fit difference is 0.0 having standard deviation from 0.22224 from the average and zero with RMS of 0.2210. The maximum magnitude of the difference including x and y together is 0.5336 and the minimum −0.5077. Thus, with a given range of surface quality specification, laser tracker is an easy and reliable measurement and inspection tool to be considered.

“…Acero et al [31] added a laser tracker and six retroreflectors to the IMP as reference equipment able to generate an infinite number of virtual lengths then used as virtual artefacts for the calibration and verification of the articulated machine arm. The uncertainty of the laser tracker and the IMP as reference equipment for AACMM calibration was discussed by Acero et al in [32]. The same author [33] proposed another verification procedure of the AACMM with the IMP mathematical model using the measurements of a ball bar gauge located in a fixed position in the instrument's working volume as a reference.…”

This paper proposes a quick and efficient methodology of uncertainty estimation on measurement results provided by an articulated arm coordinate measuring machine (AACMM). The methodology is highly adapted to industrial applications—a frequent use of these devices—but can also be performed in laboratories. The study stems from an actual need among coordinate measuring arm users to estimate the uncertainty associated with their equipment in specific conditions on the shop floor. It is important to mention that no simple and quick test exists currently to estimate the measurement uncertainty of results obtained with an AACMM in the conditions of the measurement site. In fact, the guidelines and studies addressing measuring machines propose protocols to verify performance or to evaluate uncertainties associated with measurement results, but these protocols are laboratory-type tests (carried out after purchase, re-calibration, etc) and usually take hours to complete.

“…Data acquisition is carried usually out by using various artifacts, for example, a 3D artifact [14] was composed of 14 reference points with three different heights, another example was a kind of ball bar used for length reference that calibration tests were carried out in larger space by changing ball bar pose [7,11]. Acero R. et al [15] used a laser tracker as a reference instrument for AACMM calibration and verification procedures. The technique increases the flexibility for defining test positions.…”

Articulated arm coordinate measuring machines (AACMMs) have been developed and applied in industrial measurement fields for more than 30 years. Manual operation is typically required during measurement, which introduces uncertain influences, such as fluctuation of measurement force, speed, and acceleration, and leads to poor reliability and reproducibility. In this paper, a novel self-driven joint model is proposed to realize automatic measurement for AACMMs. A self-driven joint is designed by combining the joint of an AACMM with a robotic arm to realize automatic rotation. A self-driven AACMM is designed using three rolling joints and three pitching joints with assigned parameters. A virtual prototype of the self-driven AACMM is established using the Adams software to simulate the driving moment of each joint. The simulation results demonstrate that the designed mechanical structure and selected devices can meet the preset requirements. Additionally, based on the proposed model, a single physical joint is developed and assembled for performance testing. Experimental results demonstrate that the model can achieve a repeatability of 1.39″ (k = 2) when the rotational velocity is less than 1.53 rad/s. Therefore, the proposed design is suitable for use in AACMMs.
