Computer-Aided Fixture Design: An Update April 1, 2010 All fixtures are designed to hold a workpiece in position firmly and accurately during a manufacturing process.
Masters of Manufacturing: Patrick J. Hanratty July 1, 2010 An early pioneer in the fields of NC and CAD/CAM software, Patrick J. Hanratty, PhD, discovered his passion for computing and programming almost by accident, answering a newspaper ad seeking programmers in his hometown of San Diego after returning from service in the Air Force during the Korean War.
Lean Techniques: Yokoten May 1, 2010 If you have never heard the term Yokoten, prepare yourself. It has been added to the Lean Operations lexicon as an important activity. Yokoten is being used by lean firms to help them become leaner. Yokoten is a Japanese term that can be roughly translated as “across everywhere.”
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.
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.
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.
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.
