Advancements in waterjet technologyWhen Jack Budd, president of Precision Waterjet, Orange, Calif., purchased his first waterjet system seven years ago, he expected most of the company's work to come from the aerospace industry, which was robust at the time. When business from that industry tapered off, he searched for new customers in the architectural, signage, and automotive aftermarket industries.

Maximizing a coil fed press: Variables that influence production speed, setupCoil-fed stamping presses are nothing new, but coil feeding processes have changed a lot since the days when press feeders were driven mechanically by crank motion. Influencing these processes are differences between transfer and progressive tooling.

The wrinkle-wiper for tube bends: How to choose and use wiper diesA wiper die is a piece of tooling used in tube bending that helps keep the bend from wrinkling. While there are many reasons and ways to use a wiper die in a tube bending maching, you should also know what types are available, their differences, and how to choose the right one for your application.

Skiving strip edges for tube and pipe producing: New equipment developments address coil preparation challengesEdge treatment of coil strip before it enters a tube and pipe mill, called skiving, is a rapidly advancing technology. Improving the coil edge before it is welded helps increase the quality of the seam join and helps prevent rejected tube or pipe.

Adaptive bending: Achieving accurate first-piece bending resultsAdaptive bending allows press brake operators to measure a bend angle during the forming process and feed the information to the numerical control. The article discusses springback and how to determine it and the fact that when air bending, 90 percent of problems result during initial setup, and only 10 percent result from springback. It also discusses using an angle control system, methods of measuring angles, and requirements for angle measurement systems.
