Materials science has opened new possibilities for designers of cars, planes and other products. Metal alloys are now as precisely engineered as they are machined. The result is longer lasting, stronger parts. But with a wider selection of materials comes risk—how can you be sure that one piece of gray metal stock is different than another? Careful warehousing procedures and paperwork only go so far.
Manufacturing job expansion resumed in September after pausing in August. The sector added 18,000 jobs last month, with 17,000 of the gain taking place in durable goods, according to a breakdown by industry issued today by the U.S. Bureau of Labor Statistics.
Sometimes, too many choices can be a problem. That might be the case today for manufacturers of medical devices, who are facing a host of challenges and opportunities. Devices are small and getting smaller. Their complexity is increasing. End users are demanding tighter tolerances.
Workers in the oil and gas industry continue to be one of the groups at the highest risk of injuries and fatalities on the job compared to all other U.S. industries. The most recent data from the Bureau of Labor Statistics (2015) revealed that out of 120 workplace deaths in the mining, oil, and gas extraction industry, 74 of them occurred within the support activities for oil and gas operations.
It’s easy to become dazed by the continuing stream of buzz words. For those of us in manufacturing, all this buzz creates a sense of impending change, but no clarity on what that change might be. Uncertainty means anxiety.
Bill Ford, executive chairman of Ford Motor Co., is now in Act III in his career at the automaker. The outcome will determine Ford Motor’s future and his legacy.
Secure, accurate workholding sets the stage for consistent machining productivity. Depending on the parts and processes involved, workholding can be as simple and temporary as a plain vise or clamp or as complex and permanent as a machined and fabricated fixture that is custom-designed to hold a unique part.
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.
