Definition

According to DIN 8586 bending is the forming of a solid body, in which the plastic state is mainly induced by a bending load. The further processing of tubes and profiled semifinished products by bending processes to workpieces with different shapes, such as rings, segments, and 3D shapes, is referred to in this context as tube and profile bending. Tubes are considered as special profiles with circular cross sections.

Theory and Application

Introduction

Bending is one of the most commonly used procedures in sheet metal processing industry and is used in different application areas. Also various profiled semifinished products with different cross-sectional shapes can be produced and further processed by bending. In addition to sheet metals, wires, strips, rods, tubes, profiles, and preformed components can be shaped by bending on various forming machines.

In the literature, the bending procedures for...
