Toyota is changing its engineering practices in an effort to halt a slide in vehicle quality. In one major shift, more engineering work will be done in house. The amount of engineering work contracted to outside firms will drop from about 30 percent to 10 percent, according to an article in this morning’s Wall Street Journal. Toyota will also reduce total engineering effort by eliminating engine options and other design variants. In another change, testing time will be stretched out, and possibly will include use of more physical prototypes.
At least some of Toyota’s recent quality problems have been caused by poor fundamental engineering execution. In a problem disclosed by Design News, Toyota says a poorly selected plastic used as friction levers in accelerator pedal assemblies caused the gas pedal to malfunction in certain weather conditions.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
