Abstract
The paper addresses the problem of ensuring the bending quality of the waveguide on an automated pipe rotary draw bending machine by winding. This bending method is currently the most common, but has limitations on the allowable values of bend angles and radii, which ensure the accuracy and quality of the bend region geometry without losing the stability of the section shape in the form of wrinkles and ruptures. Modern requirements for minimizing dimensions and masses require the use of the minimum possible bending radii, which depend on the geometry of the section and the material of the work piece. Calculations to determine the limits of permissible bend parameters using general or special purpose programs are very time-consuming require high-performance computers and high qualification of the computing engineer. To solve this problem, it is proposed to create support software that, based on interpolation of results of more accurate calculations, allows you to determine the areas of permissible bend parameters for the selected shape and section dimensions, as well as the work piece material. This approach allows you to quickly obtain solutions for both the engineer in the design of the structure and the operator of the pipe bending machine and to obtain a product with guaranteed bending quality.
