Assessing the arcLarge-radius bends are used in many places, such as appliance handles and automobile components. For measuring large-radius bends, fabricators have at least three options: go/no-go fixtures, entering the bent part’s measurements into a CAD program and using it to calculate the radius, and a...

Get the slug outPunching a hole in a tube is one thing; getting the slug out is something else altogether. Even if most of the slugs exit without a problem, the occasional hanging slug can cause a serious problem. Two methods are mechanical force and air pressure.

Sizing up the jobAccounting is straightforward, but it’s not iron-clad; fabricators have latitude in the accounting system they use to bid on contracts. A bottom-up approach, one that analyzes all the costs that go into making a component, is suitable for many parts. A top-down approach looks at the part and...

The axis of safetyA tube bender can be considered a collection of power presses and, as such, it needs more than just a few conventional barriers between the operator and the machine. Safety mats, interlocked switches, emergency-stop switches, and interlocked side plates are a few of the safety devices available...

Feeding the processWhether a bending process starts with a cut length of tubular product or a coil, gravitational or torsional forces can lead to unwanted variations in the finished product. In the case of gravity, tube supports can counteract it; for torsion, it’s a matter of matching the coil’s output to the...

Doing more with lessLoading and unloading tube for fabricating often is a manual process. Because labor rates in the U.S. are higher than those in many other countries, manual loading and unloading isn’t competitive. Using an automatic loader/unloader can change that, moving an operation from red to black.

Coax FactsContinuous improvement and statistical process control are useful,time-tested techniques—they have been used since the 1950s—buttheir use must be tailored to specific applications. For example, atypical manufacturing metric is parts per minute, but many rollformers should measure feet...

Serpentine bending in productionBending serpentine profiles—successive 180-degree bends, which typically are used in refrigeration systems—can be a challenge. By their nature, they tend to cause interference among the various bend dies, and they can be difficult to handle. Good planning in selecting a bender,...

From the CAD station to the production floorConventional tube bending data, regardless of format, is entered manually and therefore susceptible to errors. A modern approach involves using a CAD system to generate a STEP file, which the CAD program exports directly to the bending machine. This method is fast and eliminates errors. The...
