Moldmaking is making a comeback, with more reshoring to North America of mold-and-die manufacturing that left for the Far East and other low-cost manufacturing centers. With faster metalcutting through high-speed machining (HSM) and improved EDM techniques, mold-and-die shops are finding innovative ways to compete with manufacturing operations in traditionally low-cost labor markets.
A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.
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.
Nesting is the process of arranging parts to be cut from sheets of metal or wood in the most efficient manner possible in order to maximize yield and speed the cutting process. By reducing scrap and accelerating the cutting process, fabricators are saving on material cost while running more jobs.
Highly realistic 3-D simulation software can greatly improve manufacturing processes, lending sophisticated visualization tools that help increase manufacturing productivity and product quality.
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.
Machining composites presents unique challenges compared to metals. Reinforcement fibers are abrasive, shortening tool life. The plastic matrix carries away little heat, unlike metal chips, and overheating can melt the matrix.
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.
(Roxbury Twp., NJ) Legionella, the bacteria that causes potentially fatal Legionnaire’s Disease, and other strains of deadly pathogens that are hosted by some cooling towers, have been substantially reduced by the development of a unique anti-microbial HDPE material introduced by Delta Cooling Towers (deltacooling.com) on September 1, 2016.
