New version of tube mill roll engineering software will be released at Tube 2006 At Tube Düsseldorf 2006 the data M Software + Engineering group will be presenting a new version of its roll design- and process simulation software COPRA® RF and COPRA® FEA RF. The new version offers a number of new or enhanced features for the tube making industry complementing COPRA’s existing software tool box for process modeling and roll design: COPRA® RF now also supports the automatic design and analysis of 4-roll fin passes and 5-roll welding passes and avoids user’s manual interaction in these specific cases. Picture: automatically designed 4-roll fin pass and 5-roll welding pass: COPRA® RF (download welding-rolls-in-COPRA-RF.jpg) Respective fin widths can not only be defined by entering either strip width, angles or fin dimensions. The fin width can now also be entered by definition of the welding “V-angle”. COPRA® RF has been calculating (even in previous versions) an optimized downhill forming strategy minimizing occurring longitudinally strain values – a main reason for strip edge buckling. The current version also allows the storage of user-defined downhill strategies in the machine setup parameters. Needless to say that these designs can be verified in COPRA’s subsequent analysis and simulation tools. A very interesting new feature is the possibility to design and model various types of rolling cages – often referred to as “the straight edge” forming method. A tube mill may easily consist of multiple rolling cages – subsequently arranged in the tube welding line. Picture: straight edge forming method can be designed and modeled in COPRA® RF (download cage-forming-in-COPRA-RF.JPG) In the production of extremely thin walled welded tubes the coil is often drawn to shape rather than roll formed. COPRA® RF offers in its newest version the possibility to integrate also drawing dies within a roll forming tool set. Respective drawing dies are handled in the design process as well as in COPRA’s finite element simulation module. This allows the analysis of the complete forming process and to predict and optimise the final tube’s properties.

A finite element simulation software module allows for an analysis of the forming- and calibration process and thus a prediction of the tube’s properties for subsequent process like bending or hydro forming. The user of COPRA® RF works in the context of a complete engineering workflow using an integrated document- and project manager based on an industrial SQL standard.
