SAE EDGE™ Research Report: Electrical Demand for Automotive Electrification Pathways

SAE EDGE™ Research Report: Electrical Demand for Automotive Electrification Pathways

Large uncertainties mean it is not clear which electrification pathway will prove most economical. Development of multiple pathways should, therefore, continue. These include statically charged battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles designed for a combination of plug-in and electric road system (ERS) supply. TheRead more about SAE EDGE™ Research Report: Electrical Demand for Automotive Electrification Pathways[…]

SAE EDGE™ Research Report: Pathways to Automotive Decarbonization

Writing this major review for SAE has been a real eye-opener. I had the privilege of working with 19 experts, many world leaders in their fields. They provided technical inputs on topics as diverse as future battery technologies, critical metal mining, the impact of particulates on public health, green hydrogen production and balancing electrical demand.Read more about SAE EDGE™ Research Report: Pathways to Automotive Decarbonization[…]

Additive Manufacturing Review for SAE

Additive Manufacturing Review for SAE

For this major review carried out for the Society of Automotive Engineers, I interviewed engineers at the global leader in additive manufacturing (AM) technology. A few of the contributing companies include EOS, Liebherr-Aerospace, Renishaw, DM3D and Norsk Titanium. I brought their views together to understand the state of the art in AM for structural aerospaceRead more about Additive Manufacturing Review for SAE[…]

Intrinsic Uncertainty: The Elephant in the Room

Intrinsic Uncertainty: The Elephant in the Room

It’s often assumed that confidence in a measurement equates to confidence a product conforms. However, we can only measure at discrete points on a surface, while GD&T relates to the entire surface. We don’t know what is happening on the surface between the measured points. This is known as the intrinsic uncertainty of the measurand.Read more about Intrinsic Uncertainty: The Elephant in the Room[…]

Low-Cost Recycled Composites for Automotive

Low-Cost Recycled Composites for Automotive

Composites offer significant advantages where high strength and low weight are required. These materials are, unfortunately, also very difficult to recycle. Composites consist of fiber reinforcement embedded within a polymer matrix. The polymer may be a thermoset, such as epoxy, or a thermoplastic, such as polyester. Separating the fibers from the matrix is a hugeRead more about Low-Cost Recycled Composites for Automotive[…]

Etalon Multiline Enables Self-calibrating Machine Tools

Etalon Multiline Enables Self-calibrating Machine Tools

Achieving right-first-time manufacturing requires regular calibration and verification of production machinery. On-machine measurement makes this even more important. Achieving rapid, automated and fully traceable calibration of machine tools is a priority for high-value manufacturing. The Etalon Multiline system gives this capability. To carry out a calibration, the machine must only move its spindle or probeRead more about Etalon Multiline Enables Self-calibrating Machine Tools[…]

Why simulation is the future of uncertainty evaluation

Why simulation is the future of uncertainty evaluation

In this article, I show that the conventional method for calculating uncertainty is not always reliable. In fact, it is generally only exact when the measurement can be represented by a simple linear equation and the input uncertainties are all normally distributed. Whenever the measurement is more complex, there will be errors in the wayRead more about Why simulation is the future of uncertainty evaluation[…]
