Therefore, if the tube bending is not handled properly, this will add time to the production process and challenge efficiency. Another characteristic of aircraft tube bending is its low production with many frequent tool changes. Aircraft tube bending can introduce added complications, using a wide range of tubing material, much of which has very poor elongation (12 to 18 percent). In addition, with aircraft tubes, there is minimal permitted wall thinning (12 to 18 percent) and collapse (3 to 4 percent). Also, the tube bending can include high wall factors of 200 plus, and oftentimes little or no straight between bends. First, this particular type of tube bending often consists of tight radius bends some of these less than 1” x D.
Typically, aircraft tube bending is characterized by a number of factors.
