The closed-loop concept has become widespread in recent years, especially in relation to the Industry 4.0 concept. The term “closed loop” will be used herein to refer to the pairing of specifications and checking (Figure 1) which all ISO standards, starting with ISO 1, the “mother” of all standards, use in relation to GPS (Geometrical Product Specifications).

When it comes to an early identification of noise problems in the drivetrain one has to take data analytics and its integration in the manufacturing process into account. The big vision here, in particular, is preventive quality. By evaluating sensor data of the machining process, it promises to predict whether a gear is ok or not ok. 

With its brand-new 300GMS nano Gear Metrology System, Gleason presents a world- first at Control Show 2022, May 03-06, Stuttgart, Germany. The capability of measuring gears at sub-micron level, executing advanced waviness analysis and evaluating gear noise using the most advanced analytical tools, make the 300GMS nano ideally suited to support automotive e-drive production with minimum noise requirements. 

Tremec and Klingelnberg have been working together with regard to tool and gear measuring machines since 1993.  They recently collaborated on transmission technology with Speed Viper machine tools.
