Folding technology makes sweeping changes: New developments in 200-year-old technologySchwenkbiegemachinen, or swing bending machines, have been in use for more than 200 years. European manufacturers began to power them with electrical or hydraulic power after World War II, when an enormous amount of sheet metal was used in the reconstruction of Europe.

Protecting dies against press system faultsThe need for die protection has existed ever since the first die was produced. The most elementary form of protection has always been an alert, dependable operator. However, an operator cannot always react to a problem before it damages a die.

Fabricator finds tubular niche: Job shop uses laser cutting to complement CNC machiningProduction Cutting Services was founded in 1985 as a machine shop to supply parts to agricultural equipment manufacturers in and around East Moline, Ill. It used saws and CNC machining centers to provide tubular parts, but later realized it needed to add more value. It purchased two lasers from Mazak Optonics Corp. It hasn't abandoned CNC machining, though. It uses the lasers to complement its other processes.

Reflections on a perfectly symmetric ellipse: Full-time sculptor, part-time fabricator overcomes bending challengeSculptor and fabricator Brett Richards of BR Sculpture, Chicago, got a contract to make a frame for an oval mirror—a length of square tubing bent to a perfect ellipse. Not knowing too much about the vagaries of bending tube, he figured he'd spend a few thousand dollars on a simple bender. After searching for months, he happened to see an elliptical shape made from square tubing in a vendor's booth at FABTECH.

Al GMAW: CC or CV?For about 40 years, a great debate in welding is whether to use constant-current or constant-voltage power supplies when using gas metal arc welding on aluminum. Constant-current power supplies made sense 30 years ago and are still used in some applications today, but for most applications, constant-voltage power supplies are suitable for gas metal arc welding aluminum.

Programming multiple robots: Operating two or more robots from a single point of controlIn many applicatios -- such as large-component welding, press-tending lines, and multiprocess cells -- running multiple robots from a single point of control assists in preventing collisions, simplifying the programming structure, and reducing integration cost. This approach also meets the American National Standards Institute/Robotic Institute of America (ANSI/RIA) R15.06-1999 safety standard.

New PC-based controls open path to better press brake utilization: Control improvements simplify operator usePress brake forming always has been a labor-intensive process. Shrinking lead-times and smaller lot sizes demand more frequent setups, which cut into productive output hours and put more pressure on manufacturing efficiencies. Fabricators need to find ways to reduce machine downtime for setup and operator adjustments.

Software brings new intelligence to press brakesThe types of press brake projects that remain in the U.S. tend to be those requiring smaller lot sizes, shorter turnarounds, and more complex shapes than those going offshore. Enter the need for smart press brakes—those with the capability to store and apply process intelligence. Today's shrinking lead times and smaller lot sizes demand more frequent setups, which cut into production hours. Graphical machine controls and offline programming can help maximize operational time by eliminating the time for trial-and-error setup and improving first-part accuracy.
