Addressing quality pain points in the machining industry, such as dimensional deviations, surface scratches, and thread damage in precision parts, Wenzhou Yihe Intelligent Technology Co., Ltd. has launched a comprehensive visual inspection solution covering all processes. The solution employs a laser triangulation measurement system to achieve a diameter detection accuracy of ±0.005mm for shaft parts. Combined with a self-developed multi-sensor fusion algorithm, it performs sub-micron-level quantitative analysis of gear tooth profile deviation and keyway symmetry errors, meeting ISO 2768 tolerance standards. The self-developed optical profilometer, equipped with white light interferometry technology, can detect bearing raceway roughness Ra down to 0.1μm, with a surface defect recognition rate exceeding 99.9%. For complex curved surface machining parts, a five-axis linkage scanning inspection system has been developed. This system uses an industrial robot carrying a high-resolution came
