Daimler may be the first vehicle maker to offer 3D-printed replacement parts, but racing enthusiasts and car collectors like Jay Leno have been using additive manufacturing and 3D scanning for many years to replace worn-out parts or to enhance their rides.
When GE decided that additive manufacturing was the way to go for making metal fuel nozzles for its new LEAP engine, the company touched off interest in other shops to move 3D printers from the design studio to the factory floor. It also stepped up the focus on safety standards for metal AM.
Batch and queue is the hallmark of a mass production system. Parts are processed, moved in large quantities to the next process, wait for their turn, are processed, and moved as a batch to the next process.
Here’s something you can cut out and hang on your bulletin board if you run a manufacturing company, large or small. I’ve spent nearly 60 years thinking about the factory floor, and here’s how I believe it should be run.
Smarter factory systems connected via the cloud are the grand vision offered for the future factories that will fully leverage the best available tools from automation, software and machine tool builders.
Northbrook, IL-based 3D printing company develops an all-new additive technology that can create functional, complex, high-strength parts out of composites.
Process improvement encompasses a wide range of tools, techniques and strategies. When properly deployed, shop-floor data collection and monitoring systems can help factory-floor managers leverage key data metrics including overall equipment effectiveness (OEE) and total effective equipment performance (TEEP) that measure machine uptime and pinpoint bottlenecks or other problems in order to improve machining performance.
Not all threaded connections serve similar purposes.The load-carrying needs of an aerospace engine support bolt in a tension assembly greatly exceed those of a simple screw that fastens a cover plate to an electrical wall socket. International thread-acceptance documents and standards recognize this basic engineering fact, and incorporate different thread-inspection requirements into their verification standards.
Taiichi Ohno is often quoted as declaring: “Without a standard, there can be no improvement.” The principles of lean do not work well when everyone is allowed to choose their own work method or work sequence in which to do a job: the outcome is unpredictable; flow and pull are impossible. This reduces throughput and the carefully crafted process develops unanticipated outcomes.
With all of its accomplishments – including world’s largest defense contractor, and a presence in all 50 states and 70 countries – you might think Lockheed Martin (Bethesda, MD) would already have mastered additive manufacturing.
