OMAX waterjet brings success to one-man machine shop

 

The composites industry has embraced waterjet machining, thanks to its relatively low operating cost, fast cutting speed, fast set-up time and “cool” temperature, that is, the process does not create heat in the material or part being cut and is unaffected by the heterogeneity of composite materials. The use of jets or streams of water to cut materials goes back hundreds of years, but the concept of adding abrasives to water for cutting harder materials took off in the 1960s and early 1970s, with several companies contributing to the technology, developing pumps, nozzles, intensifiers and especially hardened orifices that could withstand the erosive action of the high-velocity abrasive grit. Waterjet precision has increased as well, as manufacturers have improved flow control. The number of companies that make and sell commercial waterjet machines is extensive; check out CW’s online SourceBook for a fairly complete list: https://www.compositesworld.com/suppliers/product/362.

This foiling racer is crazy fast thanks to composites

 

I found in my inbox last week a picture like this one illustrating a blog by Jake Kavanagh (May 24, 2018) in the Epoxycraft newsletter —Epoxycraft is published by West System International (Romsey, UK), the maker of well-known marine epoxies WEST SYSTEM and PRO-SET under license from Gougeon Brothers Inc., now known as West System Inc. (Bay City, MI, US). The blog described the Exocet racer (Moth class) built by Maguire Boats (New Milton, Hampshire, UK) and it spurred me to do some research on how it is possible to do what the guy in the picture is doing.

In Sweden lightweight is one of the country’s strategic innovation areas. The LIGHTer (Mölndal, Sweden) network works to coordinate what is happening in research, development, technology and competence development in Swedish industry.

LIGHTer calls itself a “multi-sectorial lightweight arena.” When asked to explain, Fredrik Stig, vice director of LIGHTer and senior scientist at Swerea SICOMP (Mölndal, Sweden), a leading research institute in the field of polymer fiber composites, describes the network as “cross-disciplinary.” The network facilitates the creation of products with low weight across industries, materials and disciplines.
