The industrial world is continuing its adoption of Geometric Dimensioning and Tolerancing (GD&T), the advanced tolerancing methodology. The symbolic language is intended to be both more precise while providing more latitude in allowable variations, replacing the simpler method of adding tolerances to each dimension.

“Five years ago, our fit and finish was below average,” said Dr. Raj Kawlra, director of dimensional strategy and management of Chrysler Group (Auburn Hills, MI). “To be the future world-leaders, we knew that we had to focus on all aspects of quality … vehicles that look good, feel good, sound good, and are reliable.”
Additive manufacturing lets companies think “outside the box.” Engineers can now start to look at a part without restrictions on size, shape or material. Instead of taking 15 different CNC milled parts and brazing them together, these companies have reimagined the part entirely—to be built as one part.
Modern manufacturing is rapidly adopting model-based definition (MBD). When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact—from design to manufacturing to inspection and quality reporting.
Micro components continue to shrink in size, demanding ever-greater precision and improved handling of parts with sub-micron-sized features. New approaches in micro machining technology include higher-precision systems from traditional micro machining developers, as well as techniques using additive manufacturing processes and semiconductor wafer-scale technology on the smallest of micro parts.
If NASA’s Journey to Mars project succeeds, the astronauts who make the 140 million-mile (225 million-km) trip to the Red Planet in the 2030s will need someplace to stay. The space agency is looking at 3D printing, using on-site materials, to manufacture humanity’s first deep space home.
While high-end metrology devices like advanced laser scanners or precision CMMs garner a lot of attention, it is hard to imagine any industrial setting without the presence of work-a-day hand-held, contact metrology tools such as calipers or micrometers. That is what Justin Frazzini, quality manager for A.A. Jansson (Waterford, MI), retailer and calibration and repair service provider, observes in his practice.
In a recent LNS Research study on the Industrial Internet of Things (IIoT) and Digital Transformation, the top two challenges facing the adoption of IIoT technology are finding the budget to invest (32% of respondents) and building the business case (30% of respondents).
As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.
NORTHBROOK, IL, Dec. 19, 2017 – UL, a global safety science company, and Tooling U-SME, a leader in manufacturing workforce and education development, announce the signing of a Letter of Intent (LOI) focused on a new collaboration to enhance workforce training and development efforts for manufacturers wanting to increase their capabilities in additive manufacturing.
