Workers' compensation—Managing the process
Editor's note: Portions of this article were published previously in an issue of FMA/TPA "Member Connections." State workers' compensation laws were enacted to ensure that covered employees who are injured on the job are provided with monetary benefits to cover medical expenses and to... Read more...

Identifying the right cutting and welding tips
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 ) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle... Read more...

Making steels stronger
As we get into modifying a steel's strength and hardness, keep a couple things in mind. First, don't confuse hardness with hardenability. A steel's maximum hardness is a function of its carbon content: more carbon, more hardness. Hardenability, on the other hand, refers to the amount of... Read more...

Virtual tryout
In this era of global warp speed and virtual reality, calculating the deep draws of progressive dies or the springback of metal is performed by simulation software instead of the earlier trial-and-error method. These software programs essentially replace the artistic methods of diemaking... Read more...

Taking the heat, keeping the current
A DaimlerChrysler powertrain control module cover/heat sink assembly needed to be thermally conductive yet electrically isolated. The populated circuit board—one with all components in place—had to be bonded to the heat sink and postcured in a vacuum laminating press. The... Read more...

Maximizing a coil fed press
Modern Coil-fed Presses Stamping processes revolve around two basic styles of tooling, transfer and progressive dies. They both require feed-to-length systems but differ in many key areas. Blanking processes could be added but are progressive in nature. Transfer tooling requires material to be... Read more...

Do you use checking jigs and fixtures?
The effect that checking fixtures have on your operating bottom line is so important that they should be given a much higher priority than most tube fabricators give them. The cost of quality checking fixtures should be included in every bid when quoting jobs. In fact, costs incurred... Read more...

Designing high-strength steel stamped parts for formability
The problems associated with forming high-strength steel often are created during the design stage, when products are designed in such a way that they cannot be manufactured using conventional stamping methods. Or the product requires numerous or special offline operations, such as annealing or... Read more...

Dealing with internal pressure in free hydraulic bulging
Finite element analysis (FEA) is a numerical process that treats a single item, such as a metal tube, as a large number of small, individual components, or finite elements. It performs calculations on each of the elements and uses the result to predict the deformation behavior of the... Read more...

10 questions to ask about equipment leasing
A lease finances only the value of the equipment expected to be depleted during the lease term. The lessee usually has options to return the equipment to the lessor, purchase the equipment at fair market value or a nominal fixed price, or renew the lease. Approximately eight out of 10...

High-speed feeding techniques
The maximum operating speed of a stamping operation should be limited, in theory, only by the maximum number of strokes per minute (SPM) that the press can achieve. In reality, production speed is limited by other factors as well. For instance:
1. The uncoiler may not unwind... Read more...

It's all about precision, craftsmanship
Consider the various applications for microwelding and some of the first images that come to mind are the highly intricate weld operations performed on hardened tool steels and machined weldments—synonymous with a high level of precision and craftsmanship. An increasingly large... Read more...

Adaptive bending
In conventional press brake bending, the bend angle obtained often differs from the programmed angle even though it is produced on a CNC machine. To overcome this problem, the bend angle can be measured during the forming process and this information fed to the numerical control. This process... Read more...

Designing progressive dies
Figure 1: This part was rotated in the strip to maintain critical tolerances better. The decision to produce a part progressively is usually determined by two factors: the volume of production and the complexity of the part. These two factors are instrumental in the design and... Read more...

Examining tube mill roll tooling, setup, and maintenance
Poor tooling setup and mill alignment can be costly, especially when they result in decreased production quality and scrap. Both areas must be maintained continuously. A secret to achieving maximum roll integrity is simple, but often forgotten: Roll tooling design is based on known parameters... Read more...

Key design principles for successful deep drawing
Successful deep drawing depends on many factors. Ignoring even one of them during die design and build can prove disastrous. However, regardless of the many factors involved, the most important element to a successful deep drawing operation is initiating metal flow. The following are key... Read more...

Cutting die-related costs: Where to look to save money
I want it cheaper. I want it better. I want it faster, preferably yesterday. The pace of business in the metal stamping industry continues to escalate. And the trend is not going to reverse. Balancing cost against quality and time can be a real challenge. Add to that the pressures of... Read more...
