Reclaiming the disappearing press brake knowledge in your shopExpensive options on a press brake won't guarantee knowledge transfer from a veteran press brake operator to a shop floor rookie. For knowledge transfer to occur, a shop needs experienced workers that can communicate and a younger work force eager to learn because they see a future in metal...

The tao of forming orderIs the starting position of the flat part facing the wrong way or upside down to your natural flow? Are you working from left to right when your natural motion is right to left? If you are, you're fighting the current rather than letting the current do the work. Set up the press brake in such a...

Taking the danger out of bottom bendingIt is all too easy to ruin a tool or upset a ram if bottom bending is done incorrectly, which is why many manufacturers do not recommend bottom bending when using their equipment or tooling. Understanding V-die selection and the effects of your decisions should be first and foremost in any...

Fighting springback in profound radius bendsWhen 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...
