Drilling Difficult Materials January 1, 2012 Drilling a hole to required specification in production drilling can be challenging when the workpiece material is especially difficult-to-machine.
Communicating with the Shop Floor August 1, 2012 For years, the manufacturing industry has debated the pros and cons of opening up manufacturing networks, but concerns over virus vulnerabilities and the stability of PCs on the network largely limited open-architecture PC controls’ progress and kept entrenched proprietary systems in place.
Materials for Medical Manufacturing May 1, 2011 Specialized metal alloys, ceramics, thermoplastics and other newer materials continue to aid aging populations
Precision With/Without Guide Bushing May 1, 2010 Last year’s surge in medical machining and firearms manufacturing could well be joined or even eclipsed by this years’ reemergence of production for applications in the automotive, aerospace, electronics, and hydraulics industries, generating increased interest in Swiss-style machining. This isn’t news. But what may be surprising is that the venerable, tried and true Swiss automatic CNC lathe coninues to evolve, adding bells and whistles where needed, or conversely stripping one—like a guide bushing—away to maximize its efficiency in machining parts complete.
Machine Tool Control April 1, 2010 Shop efficiencies start with the machine tool controller, as today’s CNC equipment offers machine operators myriad tools for improving part surface finishes, allocating machine time, and cutting job cycle times.
Tooling It Up for Composites April 1, 2010 From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.
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.
Machining with Robots November 1, 2009 Robotic machining technology has advanced to where it poses a serious alternative to metalcutting applications on more traditional machining centers. With the latest robotics equipment and related software, automation suppliers and robotic system integrators are gaining some traction using robots in many material-removal applications previously done only with machine tools.
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.
When Clamps Aren’t the Answer August 1, 2008 Workholding techniques using a magnetic field, a vacuum, or an adhesive can be effective alternatives to clamps. When these techniques are used, more part area is available for the cutting tools, thin parts can be held, and initial setup can be fast and simple. Plus, there is a potential for smoother surfaces and a shorter overall production cycle.
