Manufacturing Methods for a Better Engine:

May 1, 2020 Billy Hurley

Before you can begin to talk about the manufacturing methods for better engines, you need to learn what’s going on inside the machinery and investigate the physics. By building a series of experimental rotating detonation engines, University of Washington researcher James Koch and his team found promising patterns in an advanced technology known as the rotating detonation engine, or RDE.

Friction Coefficient Evaluation on Aluminum Alloy Sheet Metal Using Digital Image Correlation

Technical Paper

2018-01-1223
The coefficient of friction between surfaces is an important criterion for predicting metal behavior during sheet metal stamping processes. This research introduces an innovative technique to find the coefficient of friction on a lubricated aluminum sheet metal surface by simulating the industrial manufacturing stamping process while using 3D digital image correlation (3D-DIC) to track the deformation.

Smart Materials:
When it comes to smart materials, Keith Goossen at the University of Delaware has a newer, cheaper idea for eco-friendly windows and windshields: Liquid. Goossen’s glass contains fluid-activated panels that change from transparent to opaque states – an achievement that he hopes will provide a more affordable, commercial appeal to consumers. The 3D-printed smart materials switch from transparent to reflective a thousand times without degrading.

Additive Manufacturing and Methods of Inspection:
There are many methods of manufacturing, and many methods of inspection. Do the same inspection methods used in casting apply to products built by additive manufacturing with powdered metal? A Tech Briefs reader asks our industry expert Kevin Brigden, an Applications Engineer at the U.K.-based engineering company Renishaw.

Siemens Digital Industries Software merges virtual and real worlds in software, hardware, design, and manufacturing
“Every industry we serve – from aerospace and automotive to electronic design – is transforming,” Siemens PLM Software officials in Plano, Texas, acknowledge. Siemens PLM Software, too, is undergoing a transformation, having just changed its name to Siemens Digital Industries Software. The new name reflects the division’s position inside the core operating company, Siemens Digital Industries, as well as its evolution from a product lifecycle management (PLM) company to one delivering a broad portfolio of industrial software and services in support of digitalization strategies at companies around the world

Air Force maintainers now use 3D-pritning to create nonstructural aircraft parts
Three maintainers of the 60th Maintenance Squadron at Travis Air Force Base in Fairfield, California were trained and certified with Stratasys F900 industrial-sized 3D printer which prints parts up to 36-by-24-by-36 inches in Ultem 9085 thermoplastic – a material ideal for aerospace applications based on its flexibility, density, strength, weight, and flame retardant properties.
