My involvement in SME and its AeroDef event began in 2014, when I first presented an Adaptive Machining Overview at AeroDef 2014 in Long Beach, Calif. At the time, the conference was relatively small in terms of attendees and exhibitors in comparison to the explosion of other engineering conferences that began around that time.
Structured light systems measure surfaces by projecting a pattern of fringes, then using cameras and sophisticated software to convert them into point clouds of metrology data. Accuracy can reach the single-digit microns over millions of points.
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.
AS A TEAM OF FOUR MANUFACTURING engineering undergraduate students from Western Washington University (Bellingham, WA), we had our minds blown within seconds of walking onto the RAPID + TCT show floor when we attended the event, April 23-26, in Fort Worth, TX.
When the Italian company JDeal-Form (Oleggio, Italy) started using additive manufacturing to apply a micronized polymer coating to the underwire tips and bra straps it sold to brassiere makers, CTO Davide Ardizzoia grew frustrated with his AM vendor’s constant lateness.
In the near absence of academic programs to teach undergraduate engineering students additive manufacturing, a California-based startup has stepped in to help fill the void through internships.
A fused filament 3D printer has saved a custom outdoor lighting manufacturer tens of thousands of dollars a year, improving operations and winning more business. The purchase also helped retain customers who would previously have gone elsewhere for specialized parts.
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.
Burrs, sharp edges, and rough surfaces plague even the most precise metal-cutting or forming process. Deburring and finishing can often be treated as the step-child of a manufacturing process, but its importance is growing as tolerances get tighter and precision devices become the norm.
