Quality Scan: Thread Inspection: Your Application Matters June 1, 2009 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.
Tooling to Match Composite Production April 1, 2009 It’s getting harder to imagine any market that isn’t benefiting from the latest developments in parts manufactured from advanced composites. “Advanced composites will arguably dominate consumer and production products, especially in the near future,” says Bert Erdel, industry consultant and executive technology advisor, Morris Group Inc. (Windsor, CT), “as they have begun to gain wide acceptance in solving energy-related issues.”
Lean Automation February 1, 2009 Lean manufacturing principles and automation systems can coexist, although many lean purists contend that lean goals conflict with using automation. Smart applications of automation, however, can result in deployment of systems that are both automated and lean, with flexible manufacturing systems that can be easily reconfigured as factory operations change.
Solutions for Difficult Machining January 1, 2009 The machining challenges for two of the most advanced concepts in cutting tool materials are pretty well known. Cubic boron nitride (CBN) tools of varying designs are being used to cut hardened ferrous metals with or without interrupted cuts, as well as welded and clad metals.
Sustaining a Lean Culture November 1, 2009 Earlier this year, at the 21st annual Shingo Prize conference awards ceremony, Autoliv Americas’ airbag module facility in Ogden, UT, was awarded The Shingo Prize for Operational Excellence. This was the second Shingo Prize won by the Autoliv Ogden Airbag Assembly (AOA) plant.
Cutting Tools for Composites April 1, 2009 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.
Advanced Materials in Automotive September 1, 2009 Advanced materials for automotive manufacturing are helping automakers build lighter, more fuel-efficient vehicles.
Standardized Work May 1, 2008 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.
Lean Efforts Capture the Shingo November 1, 2007 A subsidiary of HNI Corp. (Mustacine, IA), the second-largest manufacturer of office furniture in North America, Hearth & Home Technologies (HHT; Mt. Pleasant, IA) manufactures sheetmetal fireplaces (both wood and gas-burning), vent pipe, and fireplace accessories. The company has four manufacturing facilities.
Advanced Technologies Supplement: Processes Reduce Composite Costs April 1, 2007 Composites engineers are expanding their craft to build more complex, durable parts at higher production volumes. One way they are achieving this objective is by using infusion-molding processes based on Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM).
