Edge Finishing — Product Enhancement or Wasted Cost? June 1, 2009 Edge finishing is a relatively new term in manufacturing. It’s a new and deeper focus on what many used to call deburring, edge honing, edge preparation, edge prepping, burring, chamfering, or edge blending. Edge finishing goes beyond any of those definitions. Deburring, which is often considered wasted effort by managers, wrongly carries a negative connotation. In reality, deburring and edge-finishing processes add many benefits to parts—they create highly desirable edge quality—the quality most products need.
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.
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.
Tool-Coating Advances Continue April 1, 2008 New coatings are going the boutique route, using multiple layers and new materials to optimize for a particular application
CAD/CAM Tools Ease Programming Complexity February 1, 2008 Advanced simulation, new toolpath techniques aid programming of highly complex machinery. CAD/CAM software developers continue to refine simulation capabilities and toolpath techniques that enable programming highly complex equipment including multiaxis and multitasking machine tools.
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.
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.
Metal Cutting: Cells and Machining Centers August 1, 2006 There will be more than one new machine introduced at IMTS 2006 that will be billed as a China beater, or as an India and rest-of-Asia beater, for that matter.
Heijunka: Leveling Production August 1, 2006 Stability on the floor, and all of the subsequent positives associated with stability, are the objectives of this lean tool
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).
