Plotting for success

October 23, 2003

By:

The butler slipped through the pantry area with the warm milk and, after adding some arsenic, served the beverage to his master. The butler had been gradually increasing the amount of arsenic over many months, so the change in the milk's taste wasn't noticeable. Soon the mistress and her nefarious servant would be rid of the one thing stopping their affair.

Take control of safety

October 23, 2003

By:

Welders are among the millions of workers who face respiratory hazards every day in the workplace. Confined spaces, solvents, and gas emissions, as well as welding, grinding, and soldering, may expose workers to airborne hazards.

Programming multiple robots

October 23, 2003

By:

In many applications—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.

Pinpointing future laser welding markets

October 23, 2003

By:

Aficionados of laser welding technology at times must feel a little like telephone vendors beamed back to 1603. They know almost everyone is going to use them in the future, but getting buy-in today can be like hawking loans at 25 percent-lots of interest and few takers.

Controlling bend angles

October 9, 2003

By:

Bend angles are among the most frustrating geometric features to control in metal stamping. This is due primarily to two factors – the inconsistency of the mechanical properties in the metal being bent and the die design.

Making steels stronger

October 9, 2003

By:

When it comes to modifying a steel's strength and hardness, it's important to not confuse hardness with hardenability and remember that hardenability characteristics are important because they help identify how much a specific steel will harden during welding.

Identifying the right cutting and welding tips

October 9, 2003

By:

The tip of a welding or cutting torch is where the action is (see Figure 1). Welding tips usually produce positive pressure (higher than 1 pound per square inch [PSI]) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle...

Eliminating final trim shearing of hydroformed tube

October 9, 2003

By: , ,

The most common way to establish tube length after hydroforming is by cutting or shearing the tube to a specified dimension; however, cutting out this step can reduce scrap. A new method designed to eliminate this step combines forming the end of a tube to resemble its final form with using a hydroform die to correct end position variations off the bender. While this approach eliminates the final shear trim operation, it also presents new challenges.

Using finite element analysis to roll-form tubes

October 9, 2003

By: ,

Roll forming is a common method for producing steel tubes. It is a continuous process in which a strip is guided through several sets of rolls that form the strip into the desired shape. After the final shape is achieved, tube edges are welded together to form a closed section. After the welding operation, the tube is sized through another set of rolls to obtain the required diameter.

A survey of presses for hydroforming tubes, extrusions

October 9, 2003

By: ,

Hydroforming is one of the most important fields in production manufacturing. In recent years many single presses, groups of presses, and entire production plants for internal high-pressure (IHP) hydroforming of tubes and extrusions have been installed, especially in the Americas and in Europe. The driving force behind this development has been the efficient production of automotive parts.
