Don't rule out plasma for cutting aluminum: Clearing up the misconceptionsIn any discussion about how to cut metal, plasma cutting is right up there with laser and waterjet. The technology gets a bad rap, though, when the discussion turns to cutting aluminum. There are five preconceptions that many fabricators have about turning to plasma to cut aluminum. But according to three experts, new plasma cutting systems produce good results on aluminum.

Minimizing wall thickness variation in seamless tubingAll mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.

Selecting a new press brakeProspective buyers of press brakes are advised to consider their purchase in terms of its end use, the amount of deflection likely to occur in a give machine, the inside radius of their parts, and several other factors before speding their money.

Why should you care about inside bend radii?Operators, designers, and engineers, why should you care about the inside bend radius if the customer doesn't? Because, ultimately, just how easy or difficult it is to produce a part depends on decisions made during the design stage. Misunderstanding terminology, process capabilities, or production methods can lead to mistakes that can make production more difficult. The most common mistake is incorrectly calculating and achieving the correct minimum inside bend radius.

The challenges of laser cutting: Overcoming some common obstaclesLasers can be used to process expensive alloys as well as traditional materials such as stainless steel. However, knowing the strengths and weaknesses of laser processing is the key to determining whether or not a laser is the right choice for cutting.

When does a punch/laser make sense?: 3 Questions a fabricator needs to askHawkeye Industries Inc., Tupelo, Miss., was getting more and more orders for parts that required both punching and laser cutting. To meet the growing demand, the company purchased a combination punch/laser machine. Some shops are more suited than others to this technolgy--combination machines can increase profits for some companies, and costs for others. Shop owners should keep five key things in mind when evaluating and purchasing a combination punch/laser machine.
