Focusing on bent tubing
You have been bending tube and pipe for years, and while you're proficient at bending, you realize that you're spending too much time on quality control. Some of the parts are easy to handle and have just one or two bends, so measuring the straight sections and verifying the bend angles isn't... Read more...

Error-free tube fabrication
In addition to detecting the weld seam, some modern electronic sensors are sophisticated enough that, when properly programmed, they can differentiate between a good weld and a bad one. Picture the activity in a typical automotive assembly plant. Dozens of synchronous industrial processes... Read more...

Draw forming
Editor's Note: This is the sixth in a series of seven articles that identify and define the need for a new processing theory for the net shape processes (of which draw forming is one) and that explain the general content and configuration that new theory must have. The first five articles in... Read more...

Gaining from friction and formability data
Figure 1 Business owners now are paying closer attention to forming lubricants. Why? Because new data has linked lubricants to an important driver of business profits—steel efficiency. With metal representing close to half of a company's total operating cost and manufacturing... Read more...

Finding and creating value in your stamping operation
Their focus on time requires that material flow smoothly through the production processes in concert with sales orders, raw materials, and purchased parts. It also requires smaller production batch sizes. Most important, these companies have learned that the greatest waste and excess... Read more...

Measuring tube as it grows and shrinks
We always have some confusion at our house concerning desserts. My wife claims that I like only two kinds of pie: hot and cold. Well, she is mostly right. My favorite is cherry, and I love it served either hot or cold. Here's our family recipe—you be the judge.
Grandma's Cherry Pie... Read more...

What's that material?
An XRF system can be integrated at a detector station before final packaging. The tubes are held in place by a pneumatic clamp while the XRF detector is raised to make contact with the tube and perform the measurement. This process confirms the alloy grade of the material typically in two... Read more...

Equipping Your Press With the Right Tonnage Monitor
Tonnage monitoring equipment has been around for several decades. The early models were sometimes finicky, hard to use, and susceptible to outside electrical interference. Today's tonnage monitors are easier to install, simpler to use, and more reliable. Many types are available to meet the... Read more...

Technology modernizes CMMs
Coordinate measuring machines have progressed since their inception in the 1970s. Original machines were benchtop-mounted, cumbersome to use, and limited to five axes. In addition, some complex tube applications required two software programs for a complete set of measurements. These days,... Read more...

Radiographic and ultrasonic weld inspection
Radiographic and ultrasonic weld inspection are the two most common nondestructive testing (NDT) methods used to detect discontinuities within the internal structure of welds. The obvious advantage of both of these testing methods is their ability to help establish the weld's internal integrity... Read more...

Gettin' down with downtime
The pressures of increased competition and the need for stampers to stay competitive affect every aspect of their operations. One of the key ways stampers can create an efficient and cost-effective operation is to reduce downtime on the shop floor. One of the principal causes of downtime... 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...
