The application is also able to check whether a certain part can be produced by simply reverting the steps and thereby starting the bending process from the other end. If the user selects a bending machine with dies of the

same radius and diameter on different layers or stacks, Kolli automatically considers these as alternatives. Collisions can also be avoided by correction feeds, with further possibilities examined by Kolli.

applications to capture an individual workshop environment. This includes the construction of a user’s own bending machine with a 3D-machine- editor, design of toolsets with a 3D-tool- editor, and collecting material data with a material-manager. The entire bending process can be visualized in the simulation, with details reviewed by pausing the animation and zooming into critical areas. In certain situations where large batches of pipes require bending, the application can be used to perform the entire simulation and calculation. The calculation focuses on the correction of the length of pipes and the computation of the right bending parameters. These parameters include the extended bending angle for spring-back correction and the shortened straight parts between the bows as correction of the stretching. The application can also calculate the relative and absolute flange positions in cases of bending with two flanges. 3R Software Solutions cooperates closely with the various manufacturers of bending/forming benches. This ensures that Kolli import and export interfaces are created for the well-known design systems and the most common bending machines. The different SPS-systems can be directly fed with bending and forming data with pipes manufactured sequentially.
