The most important parts of lean implementation are preparation—especially an objective assessment and development of the business and technical cases for lean—leadership that can get things done, appropriate training, resolution of people issues, and well-designed deployment methods.

Advanced technology in the metal stamping industry has rendered obsolete traditional methods of selecting, specifying, and supplying material. Using modern technology to quantify materials can reduce the occurrence of material variation exceeding the die and process capabilities and make die development a much more efficient process.

In draw forming, measurement and quantification are essential to ensuring part quality for the customer. However, the product requirements and the product input variables have different metrics and different conceptual meanings, which seems to defy direct engineering. Three processing variables can be adjusted during production to ensure the part is formed correctly.
Vault-structured sheet metal undergoes very little strain hardening during structuring, so it can be deformed further into shapes such as cans, containers, washing machine drums, thin-walled detector tubes, heat exchangers, and light reflectors.
Although the last step in the bidding process is to submit your bid, your final step in working with the government is never to give up and to apply what you learned throughout the process to every government job opportunity.

The ironing test developed at the ERC/NSM reproduces production conditions of contact pressure up to 94 kilopounds per square inch (KSI) and temperatures up to 300 degrees F to quantitatively evaluate lubricant performance.

In recent studies, dry-film lubricants have been shown to give better lubrication conditions compared to oil-based liquid lubricants. This factor, as well as savings in the amount of lubricant used, has helped increase the use of dry-film lubricants in the automotive industry for forming of aluminum and high-strength steel stamped parts.

Hydroforming has become a favored technology for automotive parts because it allows manufacturers to increase a component's strength, reduce its weight, and reduce the number of parts in an assembly. Another important benefit, one that is often overlooked, is the increase in design freedom this technology allows. Engineers and designers must be aware of the factors that restrict design freedom, such as material characteristics and press limitations, and alternatives such as annealing and axial feeding that help work around these limitations.
Five types of nondestructive testing are common for tube and pipe weld inspection, and each has advantages and disadvantages that may make one more suitable than another for your inspections.

Bud Graham revisits his January/February column on problems that plague tube mills (or nearly any manufacturing company, for that matter) and shares some reader feedback. Also, he provides the runners-up and winner of a caption contest for a photo that also appeared in the January/February issue.

In any stamping process including progressive dies, transfer dies, or line dies, three factors are essential to consider when processing a piece of flat metal into a finished part: What is the metal? What is the metal's thickness? What are the part tolerances?

As oil hovers around $60 per barrel, SUVs aren't that cool anymore. Many view them as dinosaurs, remnants of '90s excess that have no place in a thriftier, more environmentally conscious century.

Although the upfront costs of installing machine safeguards can be expensive, it is far more expensive to put your company at risk for employee injury and the resulting medical expenses, lost production, fines, and lawsuits.
