“…With the rapid development of harmonic drive technology, a variety of tooth profile measuring methods have been reported, including contact and noncontact methods: the three-coordinate method, stylus profiler methods, laser interferometer method, chromatic confocal method, structure light method, visual image method, and so [ 5 , 6 , 7 , 8 , 9 , 10 , 11 ]. Among these methods, the laser interferometer method, structure light method, and visual image method can only provide the maximum section profile with limited visual field, lateral resolution, and systematic imaging aberration.…”

A hybrid strategy is proposed to meet the challenge of obtaining the profile of micro gear teeth with a small modulus. Firstly, the contact probe segmentally obtained the falling flank profiles with an auxiliary lifting mechanism to avoid interference when it climbs on the rising slope. Then, the noncontact chromatic confocal displacement sensor efficiently acquired the gear peak positions to carry out the two-point error separation with the gear peak positions from the probe measurement. Finally, actual experiments were carried out to obtain the profile of a harmonic drive flexspline. Compared with the commercial ultraprecise profiler, the proposed method provides measurement results with a deviation of less than 20 μm. In conclusion, the hybrid strategy is feasible and accurate for drawing the micro gear teeth profile without any collision between the measuring probes and the measured workpiece.

“…However, the paper did not provide the specific effect of laser line reflections on the measurement results or the corresponding compensation methods. Wang et al [7] proposed an incoherent line structured light tooth profile measurement method, developed a corresponding measurement system, and conducted tooth profile measurement experiments using an involute master. However, only the involute master was experimentally tested in the paper, and the problem of structured light occlusion by adjacent gear teeth during the measurements was not considered.…”

As an advanced metrology technology, three-dimensional (3D) gear measurement using linear laser techniques is susceptible to the influence of multiple coupling factors. Consequently, there exists an urgent need for new principles to effectively decouple the effects of each factor. Digital twins realize the connection between physical and virtual spaces. By fusing multi-source data from the existing system, a highfidelity digital model is established to realize the simulation of the gear measurement process in this paper. Moreover, simulation of the light reflections of tooth flanks and the dynamic error coupling process can effectively clarify the coupling mechanism of measurement errors. This paper presents a method of constructing a digital twin model of a 3D measurement system for gears and realizes the expression of the actual measurement processing. It provides the foundation for subsequently studying the reflection characteristics of the tooth flank at different incident angles and searching for the optimum incident attitude of the line structured light sensor.INDEX TERMS digital twin, model construction, multi-source data, gear measurement.
