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).
Automation in Lean Manufacturing July 1, 2007 Common misperceptions about lean manufacturing and automation systems lead many manufacturing managers to dismiss the use of automation in a lean setting.
Lean at NUMMI September 1, 2005 To remain competitive in the fiercely contested North American automotive industry, the New United Motor Manufacturing Inc. (NUMMI, Fremont, CA) assembly plant, a joint venture between Toyota Motor Corp. (Aichi Prefecture, Japan) and General Motors Corp. (Detroit), has rededicated its efforts in lean manufacturing during the past few years by applying key tenets of the Toyota Production System (TPS).
Programming CMMs May 1, 2004 Off-line programming software tools for CMMs allow manufacturers to increase measurement capacity and throughput by programming CMMs, probes, and fixtures before parts are made.
