The bending technology area includes all manner of machines and processes for bending sheet metal, including press brakes, folders, panel benders, corner formers, ironworkers, notchers, orbital formers, and roll benders. It also has information on accessories such as gauging and backgauging systems.

Adaptive bending allows press brake operators to measure a bend angle during the forming process and feed the information to the numerical control. The article discusses springback and how to determine it and the fact that when air bending, 90 percent of problems result during initial setup, and only 10 percent result from springback. It also discusses using an angle control system, methods of measuring angles, and requirements for angle measurement systems.

The article discusses making small holes and when to use a punch or laser cutter, inside radius measurements and how they differ depending on whether you are coining or air bending on a press brake, and adding bend relief to prevent tearing material.

What sort of safety measures needed in your shop depends somewhat on your equipment, but making your press brake a safe piece of equipment is largely a matter of old-fashioned common sense.

When bending sheet metal, three terms apply to the radius of the bend: sharp, radius, and profound. A sharp bend has a radius less than 63 percent of the material thickness. A radius bend has a radius between 63 percent and 10 times the material thickness. A profound radius exceeds 10 times the material thickness and an entirely new set of rules apply. This article presents those rules.

Prospective buyers of press brakes are advised to consider their purchase in terms of its end use, the amount of deflection likely to occur in a give machine, the inside radius of their parts, and several other factors before speding their money.

Plainly put, press brake safety is a common sense issue. Most accidents are caused by operator inattentiveness or lack of training. Two major categories of press brake safety are machine setup and operational safety. Along with proper tooling selection, applied tonnages, and installation, you...

When the right technology is available, manufacturing small lot sizes can be a shrewd business strategy. Three developments are bringing automation to press brakes and, as a result, are helping fabricators meet customers' demands for smaller lot sizes.
