Materials Matter: Additive Manufacturing: Challenges, Possibilities, and the Gear Industry
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 reduction in scrap metal, has obvious benefits.

ISF Surface Versus Machined Surface
Why ISF® Surfaces are superior to machined surfaced: As the load of the mating surface is increased, the lubrication film becomes thinner, and the asperities of the machine surface contact each other resulting in plastic deformation, metal debris and scuffing, not so with REM Surface Engineering’s ISF® Surface.

Gear Corrosion During the Manufacturing Process
No matter how well gears are designed and manufactured, gear corrosion can occur that may easily result in catastrophic failure. Since corrosion is sporadic and a rare event and often difficult to observe in the root fillet region or in finely pitched gears with normal visual inspection, it may easily go undetected.

High Speed, Automatable Superfinishing of Rear-Axle Hypoid Gears
The benefits gained by superfinishing rear-axle hypoid gearsets are now well documented. Friction, wear and operating temperature are significantly reduced. The main impediment to commercially implementing this process, however, is that it increases manufacturing cost in terms of process speed, work in process and labor.

The Effect of Superfinishing on Gear Micropitting, Part II
It should be noted from the outset that the data presented in Part I and Part II of this paper was generated by independent laboratories. Superfinishing of the gears was the authors’ sole contribution to these studies.
