4 Factors Influencing Cut Edge

4 Factors Influencing Cut Edge Quality (and Why it Matters Anyway) When cutting metal there’s usually a lot of thought given to speed and accuracy. Those are important but we’d argue edge quality is another factor to consider. It’s also one that doesn’t get the attention it deserves, except here at Wiley. We think about…

Forming aluminum on the press brake: Bending soft, not sharp

Q: I came across a bending issue that has me completely baffled. I have 0.984-in. die and a 0.03-in. (1-mm) punch. We were working with 0.125-in.-thick 6061-T6 aluminum, but we were experiencing cracking problems, so we switched to 1100-O aluminum, with a specified tensile strength of just 13,000 PSI. According to the 20 percent rule, I…
