Safeguarding machines with an ergonomic spin Figure 1 While the NSC publications provide generous guidance, two aspects they do not address fully are the application and implication of ergonomics and human factors in the design of machine safeguards. The National Safety Council (NSC) published the fifth edition of the Power... Read more...

Gear up for welding I'm sitting here at this computer realizing how much I hate sitting here at this computer. I'm just not a sit-in-a-chair type of guy. I tried it once between jobs. I interviewed for an inside sales position for a company that sold welding supplies. I'll be danged if they didn't hire me,... Read more...

Selecting a stamping die pressure system, Part I Selecting the stamping die's pressure system can be a critical decision. Many questions must be answered to determine what type of pressure system best suits your application. Controlling Factors 1. Pressure requirements Simple conventional metal cutting dies, such as those used in blanking... Read more...

The history of welding according to Marty OK, so this guy back in ancient times got into a fight with another guy. He got punched in the eye and fell backward, hitting his head on a fallen tree branch. He thought to himself, "That fist hurt, but that dang tree limb hurt worse." (This was the first time the expression "dang" was... Read more...

Controlling bend angles Spring-back Analysis All metal has a certain amount of spring-back. Spring-back, also known as elastic recovery, is the tendency for the metal to want to return to its original flat blank shape after being bent. To fully understand why metal springs back, we first must understand that metal,... Read more...

Metal stamping and electromagnetic forming: New process improves material formability, reduces wrinkling Object Research done at The Ohio State University during the past several years has shown that when material is stretched at high speed, it is less apt to tear than if it is stretched slowly. This is because the action of the material tearing causes a change of direction. If this is done... Read more...

Huge possibilities, tiny tools Nanotechnology--the science of small--could change the metals industry in a very big way When comedian Steve Martin told his audiences "Let's get small" in the 1970s, nanotechnology probably registered just above "jab eye with hot poker" on his priority list. However, nanotechnology and nanoscience—the application and study of particles one-billionth of a meter wide—now... Read more...

Die design for flat parts: Achieving perfection in a difficult task Flatness is one of the most difficult part characteristics to achieve in a conventional stamping die. Some of the factors controlling part flatness are: 1. The severity of the steel cutting deformation. 2. The mechanical properties of the sheet material. 3. The incoming flatness of the...
