Masters of Manufacturing: Herbert B. Voelcker July 1, 2009 A self-described “river rat” during his teenage years, Herbert B. Voelcker grew up in the small town of Tonawanda, NY, just north of Buffalo, where as a young man he grew to love the water, boats, and steam engines. His early fascination with how things worked eventually led him to study mechanical engineering at the Massachusetts Institute of Technology (Cambridge, MA), and to embark later on a greatly varied technical career highlighted by his research into the mathematical foundations for 3-D solid modeling.
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.”
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.
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.
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).
Masters of Manufacturing: Joseph M. Juran July 1, 2005 Considered by many to be the “Father of Quality Management,” Dr. Joseph M. Juran is recognized as the man who added a human dimension to quality, expanding it from its statistical origins to a broader management science.
Machine Components/Cleaning/Environment/Fluid Power and Other Manufacturing Equipment August 1, 2004 Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
Masters of Manufacturing: M. Eugene Merchant July 1, 2004 M. Eugene Merchant began his career in 1936 at the Cincinnati Milling Machine Co. (later Cincinnati Milacron), where he went to work analyzing the nature of friction between the cutting tool and the chip. The young engineer eventually developed a mathematical model of the metalcutting process that is still taught and used today.
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.
