Up Close and Personal

After more than two years of COVID isolation, it feels good to be getting out of our bunkers and interacting with people again. Last month, I had the great pleasure of attending the AGMA Annual Meeting, where executives from member companies got together in person for the first time since 2019. The 2020 meeting was canceled at the last minute due to COVID. Last year’s meeting was held virtually, with an electronic meeting room and videoconference presentations. But this year felt like a return to normal.

The Numbers Game

Nanofluid improves machine performance one particle at a time
May 19, 2022
Matthew Jaster

Tool-X is a nanofluid that changes the characteristics of existing metalworking fluids by ‘manipulating’ speeds, feeds and metal removal rates using nanotechnology. The science behind Tool-X can potentially change metal cutting dynamics, improve surface finishes and extend tool life. The backstory of this technology is just as fascinating as its production results.

Ear-to-Gear Ratio: An Uncanny Valley of Sound

What will the future sounds of vehicles be?
May 19, 2022
Aaron Fagan

When it comes to noise, vibration and harshness (NVH), I’m reminded of that dog-van scene from Dumb and Dumber where Jim Carrey says, “Want to hear the most annoying sound in the world?” and then proceeds to emit an astonishingly awful noise. Annoying as NVH may be, it’s a key metric in drive-system development for e-mobility, and the careful design and manufacture of gears are crucial to minimizing NVH as tolerance variations can result in large differences between nominally identical components.

Hobbing and Chamfer Cutting

Efficient, Flexible Gear Manufacturing on a Single Machine
May 18, 2022
Gottfried Klein

It wasn’t long ago that cylindrical gear chamfering and deburring was almost an afterthought. Now the process ranks as high in importance as hobbing, shaping and grinding. Seemingly every gear manufacturer, particularly those developing transmission gears for e-drive applications, recognizes that anything less than a flawless tooth flank can result in premature transmission failure, less-than-optimal efficiency, and unacceptable noise. Thus, generating a chamfer to precise customer specifications is critical to minimize the potential for sharp, brittle edges after heat treat; avoid edge load situations in the gearbox; and eliminate excessive stock and hardened burrs in the tooth flank prior to the hard finishing operations (conditions which can greatly diminish tool life).

3M Technologies Address E-Mobility Trends

April 28, 2022

The automotive industry is evolving. The trend toward more electromobility is also changing the way cars are being manufactured. In some cases, this has a serious impact, not only on automakers themselves, but also on suppliers. Jürgen Hechler, Global Application Engineering Leader at 3M, is nevertheless confident: "We expect the demand for high-precision abrasives to continue to grow, despite the discussion about electromobility." Among other things, 3M supplies the automotive industry with abrasives for machining gears and shafts.
