Laser tube processing

November 20, 2003

By:

The introduction of lasers to the manufacturing process has changed the fabrication of tubing. Today, many manual processes can be replaced with laser processing techniques. Using the flexibility afforded by lasers, a bundle of raw tubing can be loaded into a laser tube cutter; parts can be cut with high accuracy, quality, and speed; and then finished parts from the machine can be sent directly to the final assembly.

By:

The engine roars to life, and Bruce Van Sant inches the motorcycle forward, stopping about 25 feet from the starting line. Alan Geetings, crew member of the Van Sant racing team, sprays the asphalt with water. Bruce revs up the engine. The engine's torque breaks the rear tire's grip on the asphalt and it spins furiously. The air is suddenly filled with a cloud of smoke and the smell of burning rubber. After heating the tire, Bruce approaches the starting line.

Choosing the right oxyfuel gas and supply system

November 6, 2003

By:

Mixing oxygen with fuel gases for brazing, cutting, heating, and welding metal has been around since the early 1900s. Oxyfuel processes have remained in use over the years despite the introduction of other metal fabrication processes, such as arc welding, plasma cutting, and laser materials processing. Finding the most economical method for supplying oxyfuel gases requires a basic understanding of the process.

New PC-based controls open path to better press brake utilization

November 6, 2003

By:

Press brake forming always has been a labor-intensive process. Shrinking lead-times and smaller lot sizes demand more frequent setups, which cut into productive output hours and put more pressure on manufacturing efficiencies. Fabricators need to find ways to reduce machine downtime for setup and operator adjustments.

March for manufacturing

October 23, 2003

By:

As the "jobless" recovery continues, the job cleansing of the U.S. manufacturing base tops 2.7 million. These millions now without jobs remain faceless, statistical footnotes to mainstream media reports about how the recession ended in 2001, production is on the rise, and how job losses are singularly attributable to productivity gains. The outsourcing of the American dream for small manufacturers proceeds unabated.

Material handling safety

October 23, 2003

By:

Handling material is a daily function in the workplace. All too often it is a task taken for granted, with little knowledge of or attention to the consequences if done incorrectly. Management and employees need to look at and evaluate how material goods are handled inside and outside their facilities. Whether the operation involves delivering or receiving material, an area should be designated for that purpose.
