<p style="text-align: center;"><img src="/ueditor/php/upload/image/20260601/1780324068136410.png" title="1780324068136410.png" alt="1.png"/></p><p><span style="font-size: 14px;">Gear inspection and noise analysis are essential for ensuring quality and efficiency in modern gear manufacturing. Increasingly stringent requirements on dimensional tolerances—often in the micron range—and noise, vibration, and harshness (NVH) performance necessitate advanced measurement and evaluation methods. Recent developments in gear metrology include the integration of single-flank testing (SFT) technologies into broader measurement portfolios. Over the past two decades, multiple SFT system variants have been developed, with ongoing advancements focusing on expanded functionality, improved measurement resolution, and higher throughput in production environments. SFT is widely used for both in-process and end-of-line inspection in high-volume gear manufacturing. The production environment presents challenges such as tight tolerances, process variability, and increasing NVH constraints. SFT methods address these by enabling continuous quality monitoring and providing real-time feedback on transmission behavior, supporting process control and optimization.</span></p><p><br/></p>
