Roughness Measurement Tips: The Scratch Pad

Posted by Mark Michaud on giovedì, Gennaio 16th, 2020 in

From the perspective of the shop floor environment, the previous Materials Matter column “Roughness Measurement Tips: 2 V 5” discussed the contact stylus 2-micron radius tip versus a 5-micron radius tip....

Vibratory Media Compositions vs. Attrition and Density

Posted by Bill Nebiolo on martedì, Ottobre 1st, 2019 in

The third in our multi-part series on vibratory processing of gears is focused on understanding how media of different compositions have varying attrition rates and densities, and why these are important in vibratory finishing of gears. ...

Selecting media for optimum vibe bowl gear finishing

Posted by Bill Nebiolo on martedì, Agosto 20th, 2019 in

Choosing the best media depends on structure and shape of the tooth flank, and whether media components should be abrasive, non-abrasive, or a blend....

Materials Matter: Nitriding’s “White Layer” and Isotropic Superfinishing

Posted by Nathan Michaud on giovedì, Agosto 24th, 2017 in

Developed in the early 20th century, nitriding has evolved into a standard process across many industrial applications. Often considered the simplest technique for case hardening, the process is commonplace in aircraft manufacturing, bearings, automo...

Materials Matter: Additive Manufacturing: Challenges, Possibilities, and the Gear Industry

Posted by Justin Michaud on giovedì, Marzo 30th, 2017 in

Additive Manufacturing (AM) is a technology that has the potential to fundamentally alter manufacturing, specifically metal manufacturing. The ability to design complex shapes, which could not otherwise be manufactured, coupled with a significant red...

Materials Matter: Gear Corrosion in the Manufacturing Process

Posted by Danny Estrada on martedì, Gennaio 31st, 2017 in

No matter how well gears are designed and manufactured, gear corrosion can occur during the manufacturing process, which may, in turn, result in catastrophic failure....

Materials Matter: Comparing Surface Roughness Parameters

Posted by Danny Estrada on giovedì, Gennaio 5th, 2017 in

Effective gear design must account for a range of potential failure modes. As discussed in previous Materials Matter columns, gear failure modes can be fatigue-based and progressive (such as micropitting) or sudden (such as scuffing)....
