Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

Nesting is the process of arranging parts to be cut from sheets of metal or wood in the most efficient manner possible in order to maximize yield and speed the cutting process. By reducing scrap and accelerating the cutting process, fabricators are saving on material cost while running more jobs.

Turning to software over paper reports does more than just save trees. Chris Mahar, Associate Editor of Manufacturing Engineering, talks with David McPhail, President and CEO of Memex Inc., about how manufacturers can utilize technology to improve efficiency, reduce downtime and boost productivity and profits across their business.

Constant refinement of medical machining from tooling design to finished product requires not only the ability to handle a broad range of plastic and metal materials but also to achieve predictable results—particularly in the face of strict regulations.

From cutting various thicknesses of sheet metal and metal plate or different widths of tubing to navigating intricate materials or process issues, some of the laser industry’s leading suppliers have weighed in with tips and insights into their novel solutions.

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.

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.

The Fabricating & Lasers pavilion of IMTS shows how makers of machine tools have to keep improving their product lineup. For one thing, customer expectations continue to rise.

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.

There’s growing evidence that some of the moldmaking business that fled the U.S. chasing cheaper sources offshore is returning. Moldmakers are not finding enough of a favorable cost differential to offset poor mold performance and the need for rework of faulty molds.
