Abstract

A proposal is made for the ribbing of large forming tools. In the software developed for this purpose the ribbing structure is pre-optimised by means of an algorithm based on the power-law approach and then post-optimised with a newly developed algorithm for the reduction of the v. Mises stress. The model, intention and functioning of the software are explained. The optimised ribbing structures are analysed on parameterised test geometries and compared with conventional ribbing strategies in respect of manufacturing suitability, casting defects, mechanical properties and residual stress.
