A Revolution in Gear Manufacturing
Machine manufacturers are working to streamline the gear-making process, to deliver a more highly finished gear in fewer steps.

Sales of cars and light trucks plummeted during the Great Recession and General Motors Co. and Chrysler emerged from government-back bankruptcies in 2009. Since then, total industry deliveries have surged, hitting a record 17.47 million in 2015, according to Autodata Corp.
In a perfect CNC world, the first part is always a good one. There’s no need for extra blanks or barstock. Setup times are only as long as is needed to swap out a few tools and load a new program. There’s never a crash, never the need to reprogram an inefficient bit of code. The operator just pushes the green button and out pops a finished workpiece minutes or hours later.
In our May webinar titled “Lasers in Manufacturing: State of the Art in 2018,” we noted the emergence of some novel technologies to produce the “holy grail” of laser welding: spatter-free joins with no porosity and, when required, highly aesthetic outcomes.
I just returned from IMTS in Chicago and my first thought was, “where will I be able to rack up all those bonus steps I got last week?” On the easiest day, I walked 7.9 miles, and I topped 10 miles on two other days. It’s easy to understand why.
For CMMs, the good times continue to roll. “One of the surprising things that has happened in just the last three to four years is the sheer volume of CMMs that we are shipping,” said Angus Taylor, president of Hexagon Manufacturing Intelligence, North America (North Kingstown, RI). “The market seems to be really exploding.”
For Dale Mickelson, Yasda product manager at Methods Machine Tools Inc. (Sudbury, MA) and author of several books on hard milling, tackling heat-resistant superalloys (HRSAs) requires the perfect combination of machine, workholding, tooling, tool paths and coolant.
To stay current with technology and peer into the future of manufacturing, take a look at our preview of IMTS—The International Manufacturing Technology Show, to be held at McCormick Place in Chicago from Sept. 10 through Sept. 15. In the following pages, ME provides in-depth examinations of each pavilion at IMTS, as well as previews of the products you will be able to see displayed at exhibitors’ booths.
Additive manufacturing (AM) pioneer Charles Hull introduced the first commercial 3D printer, the SLA-1, in 1987. Jaws dropped, machinists wondered about their next career, pundits said it spelled the death of traditional manufacturing. None of that happened, thankfully; in fact, some said 3D printing was a bunch of hype, good for little more than investment casting patterns and proof of concept prototypes.
Most anyone attending IMTS 2018 is well aware that machine tools are the lifeblood of virtually any manufacturing company. Without lathes and machining centers, parts don’t get made, barstock collects dust on the shelf, and machinists…they’d have nothing to do.
