Optimizing a single probe, gap-tolerant, double sheet detector system

December 11, 2007

By:

Detecting the presence of two sheets in a press feeding operation uses scientific principles, but the process is not an exact science. A typical press-feeding situation involves an air gap between the detector and the first sheet in the stack or an air gap between the top two sheets, and these air gaps reduce the detector's effectiveness. Understanding the capabilities of the detector and the limitations imposed by imperfect conditions can help stampers set up an effective double-sheet detector system.

Maximizing your shop floor automation investment

December 11, 2007

By:

In the world of shorter-run and engineered-to-order production, fabricators want to keep their machines at near or full capacity, which means the business is making money. To accomplish this, the flow of information coming out of the front office has to be fast enough to drive the shop floor automation.

Choosing between feeding your new stamping line coil or blanks?

December 11, 2007

By:

Stampers today need to process more grades and types of material than ever before, yet are under relentless pressure to reduce costs. They increasingly rely on systems integrators and equipment suppliers to design and install versatile stamping lines with quick-change capabilities. A notable case was that of a truck frame and chassis components manufacturer. It worked with vendors to develop a line that processes material up to 0.280 in. thick and 72 in. wide, in a range of yield strengths, in three forms – coil, blanks, or sheet.

Surveying suitability of welding processes for roll formed parts

December 12, 2006

By:

Of the many weld processes used, resistance, high frequency and fusion welding are the most likely to be integrated with roll forming. Welding processes that are integrated with roll forming include GTAW, fusion, plasma arc welding, laser welding, resistance welding, and high-frequency welding. The fusion weld processes most successfully integrated with rollforming are those that are fast and don't require a filler metal.
