In-cycle bend measurement avoids scrap

Unison has developed a laser measurement module for its all-electric tube bending machines that dynamically measures the accuracy of bend angles and automatically compensates for any errors.
It allows manufacturers to bend tubing to the required angles without scrap - overcoming the common problem caused by variances in the 'spring back' characteristics of materials from different metal production batches with minor differences in grain and temper. The new module is targeted at manufacturers of precision and high-value tubular parts, such as those used in shipbuilding applications.
"All-electric tube benders were developed to provide users with rapid and accurate software-controlled set-up between batches. This new measurement system further enhances the ability to create parts right first time, catering for users with applications demanding the highest precision," says Alan Pickering of Unison.
He adds: "The impact of this new tool could be very significant for some manufacturers. If they use exotic alloy tubing, elimination of scrap could mean a return on investment measured in weeks. It could equally allow manufacturers to save money by changing their production methodologies, by moving from a batch production process to just-in-time fabrication for instance. Following trials, our first user has decided to dispense with a previous historical record system that documented the spring back characteristics of material batches."
