June 3, 2013

By:

In air forming, the bend angle does not depend exclusively on the angle of the die. So why does the die angle change? There are two separate but overlapping answers; one relates to narrow die openings, and the other pertains to larger dies.

Tooling changeover can be a pressing issue

March 7, 2013

By:

Press brake manufacturers have responded to industry’s need to produce small batches of parts that require frequent tooling changes by designing options and systems to reduce setup time by managing, storing, and automatically changing upper and lower tools. Operators can spend less time physically involved with setup and more time with the profit-making bending process. Reduced margin for error and less scrap are added benefits. However, there are steps that can be taken to reduce setup time without investing in new press brake equipment.

Bending for the internal customer

October 12, 2012

By:

Freeing a bending bottleneck can backfire if it simply creates a severe bottleneck downstream. Bending throughput may increase, but overall throughput--the metric that really matters--may not. That’s why the best bending automation considers not only the bending department but also the throughput of the entire plant.
