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.
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.
Even though it’s been around since the 1950s, when engineering-grade resins were first introduced, many manufacturers still are not familiar with the many benefits that metal-to-plastic conversion provides.
Today’s products require high finishes, burr-free edges, freedom from contamination, and often close tolerances. Electropolishing provides all of those conditions and more in a matter of seconds for many metal parts. It is a process that has been used for more than a hundred years. It is widely known and the science is widely discussed, but its ability to run job shop lots and high-precision high-volume parts in the same equipment makes it a bit unique.
Sales of cars and light trucks plummeted during the Great Recession and General Motors Co. and Chrysler emerged from government-back bankruptcies in 2009. Since then, total industry deliveries have surged, hitting a record 17.47 million in 2015, according to Autodata Corp.
The ongoing digital transformation of manufacturing comes baked-in with many uncertainties, and the automotive business is no exception.
There are pros and cons to using a scaffold for tissue printing. Ultimately, it’s not a matter of choosing one method over the other, but using them to complement each other.
Challenged by an increasingly niche-oriented automotive market, The Chrysler Group (Auburn Hills, MI) must increase the number of models it offers while decreasing its capital investment. The company plans to offer 50% more models in 2009 compared to 2004, according to John Felice, VP of manufacturing, technology and global enterprise for Chrysler.
Automation in manufacturing is more important than ever, reducing costs and improving quality. While it is important in assembling cars, machining engines, or drilling holes in airframes, is it important to metrology operations as well? “Absolutely,” explained Michael Kleemann, engineering manager VRSI (Plymouth, MI).
Shops today must track or measure their manufacturing operations to improve them. This need drives the growing use of MTConnect—an open, royalty-free protocol for extracting data from practically any piece of equipment, including machine tools and other manufacturing systems. The integration of MTConnect is a major undertaking, and can be a bit challenging unless certain preparations are made ahead of time.
