Improving Rotary Draw Bending Process by Changing a Geometry of the Pressure Bar [PDF]
Manufacturing Technology, 2021 The paper is focused on an analysis and optimization of the rotary draw bending process to eliminate bent tube ovality by modification of the pressure die geometry. The bending process is realized on Wafios CNC bending machine. A tube that is bent for an automotive application is made of 34MnB5 steel.

The way forward in rotary draw bending: a review
, 2023 Presently, Rotary Draw Bending (RDB) process is one of the most common tube bending techniques used in industrial production around the world. The process is executed on a specially designed machine being fitted with specific forming tools. The quality of final products in RDB largely depends on process parameters being selected by the machine operator.

Design of a fuzzy controller to prevent wrinkling during rotary draw bending [PDF]
ESAFORM 2021, 2021 Rotary draw bending (RDB) is a forming process that is commonly used to bend tubes with small wall thicknesses and small bending radii. One of the limitations of this process is the formation of wrinkles caused by compressive stress on the inner bend.
