One way to avoid dimpling and deburring while making holes in tube and pipe is use annular cutters. Because annular cutters are hollow, there is no dead-zone resistance to overcome. Knowing how to use an annular cutter and what to watch for can help avoid problems and extend tool wear.

Spray systems often are regarded as simple on-off valve and regulation systems. In reality, though, spray nozzles are precision components designed to yield very specific performance under specific process conditions. Just because nozzles are spraying doesn't mean that they are spraying precisely, and precision spray performance makes a difference in throughput, quality, and bottom-line profits

This study illustrated that, when the thickness and stress-strain curve of the sheet material are known, it is possible to predict with acceptable accuracy the bend allowance, springback angle, and punch stroke to obtain the desired final product dimensions.

When BMW Dingolfing (Germany) decided to modernize one of its transfer presses, the desired benefits included increased line availability, increased production through the use of an electronic transfer system, and reduced maintenance. However, one of its highest priorities was to minimize or eliminate the risk of production loss caused by interruptions to the power supply.

Being a good welder often means more than on-the-job performance. Whether it's volunteering to help others or otherwise giving back to one's community, these welders are examples of so many who take their time to give of themselves on the job — and outside the office.

The increased use of coated steels has resulted in an intensified search for solutions to the problems posed by joining these materials. High levels of spatter and welding fume, weld porosity, and poor bead shape are common. These problems lead to increased post-weld cleaning costs, reduced quality, greater rework, and an overall reduction in productivity. The right wire size and type, matched with the most appropriate shielding gas, can substantially improve gas metal arc welding (GMAW) performance on galvanized and coated steels.

As manufacturing has moved overseas, the U.S. slitting market has become saddled with overcapacity. Coil processors can improve efficiencies by upgrading the equipment they use in the following areas: coil storage, changeovers in coil and slitting tooling; scrap handling; and tensioning.

The 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.

Reducing weight while maintaining or improving functional requirements is one of the major goals of automotive design and manufacturing, as it decreases fuel consumption and improves structural design. As a result of these considerations, the use of aluminum alloys in car manufacturing continues to increase, not only in body panels but also in structural, power train, and suspension components.

Using oversized V dies in bottom bending can damage press brakes and tooling, but used properly, these dies can help compensate for springback.
