In an automobile engine, seven types of screws out of approximately 70 are considered critical to achieving the engine’s specified design performance, despite high vibration and heat. The seven include bolts for the cylinder head, crankshaft, con rod, flywheel, and main bearing cap, as well as for the camshaft cap, camshaft sprocket and VCT.

Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.

The first kilowatt-class fiber laser for material processing was introduced by IPG Photonics in early 2002. Since that time, the adoption of fiber lasers for production applications has grown at a rapid rate. Today, fiber lasers are becoming the choice for most major production laser applications as well as converting traditional welding and cutting processes to fiber laser technologies.

With much faster processing speeds and higher quality, you might think laser welding would quickly take over the field. But traditional welding hangs on. And depending on who you ask and what applications you consider, it may never go away.

It’s amazing what you can learn at a trade show. Editor in Chief Alan Rooks was reminded of this at the recent EASTEC show. He reflected on his visit with Joe Stanford, vice president, engineering and applications support for Applied Measurement Solutions LLC, Bristol, Conn., the largest metrology distributor for The L.S. Starrett Co., Athol, Mass.

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.

Voestalpine Eifeler Coatings announced today the opening of their newest coatings facility in Walnut, California. The new facility is located to provide Physical Vapour Deposition (PVD) coatings solutions to the manufacturing communities in California and the Western United States, according to the company.

With the new ByStar Fiber 12kW, high speeds and a large spectrum of applications are possible. The ByStar Fiber from Bystronic is being enhanced with a 12kW Fiber laser and a newly designed cutting head which enables the “BeamShaper” option, enabling consistent cutting quality on varied material qualities up to 1.125 inches.

Simulation in manufacturing is becoming much more pervasive. Advanced visualizations are used everywhere, from machining on shop-floor CNCs to offline CAD/CAM programming of NC equipment.

Metalworking machines are fast, powerful, and accurate, but they weren’t always as capable as they are today. Modern equipment is more nimble, flexible and adaptable. The machines collectively exceed the sum of their parts.
