Gauging challenges on the press brake

Gauging can make or break a bending operation, especially when working with tight-tolerance or unusually shaped workpieces. Sometimes a part is simply impossible to gauge, even with a 5- or 6-axis backgauge system. If you’re an experienced operator, you could gauge the part properly using a few gauging tricks, like laser stitching or pin gauging,…

The press brake questions keep coming

In any given month, I receive quite a few emails and letters from readers throughout the world. While I respond to some, I receive far too many to respond to all of them promptly. For those who have been waiting, I apologize for the delay, and I hope that my tardy answers are still of some value…

Press brake forming insights: The return flange goes deep

Fabricated parts made from sheet metal range from the simple to the very complex. Most part designs are relatively simple, which allows them to be produced with straightforward bend sequences and commonly available tooling. Still, while CAD can capture a seemingly limitless number of creative ideas, not all can be translated into formed sheet metal….

The hidden yet important differences in press brake tooling

Question: Machine vendors often tout the importance of buying precision-ground tooling instead of planer tooling for machines that boast high levels of accuracy. Beyond the accuracy argument, though, are there implications regarding setup time, especially when it comes to staging multiple toolsets in a single setup? Answer: As an instructor, I can’t count the number of times…

Metal folding’s place in the forming department

Walk into most commercial or precision sheet metal operations with CNC metal folders on the floor and you’ll probably find a collection of CNC press brakes too. Sure, press brakes have a long history in U.S. metal fabrication than folders do, but that’s often not why fabricators keep both types of forming machines on the…

The sheet metal bending department evolves

A decade ago most spending in precision metal fabrication—outside welding and consumables—occurred in the cutting department as the industry transitioned from low-powered CO2 lasers to high-powered CO2 and, finally, to solid-state technology. For the right application, a fiber laser today can run circles around a high-powered CO2 laser purchased a decade ago. Each November at the FABTECH® tradeshow, the…
