to its parametric structure. The lineal beams are either predefined or – if there are single mounted rolls – each roll and respective position is defined in specific database tables. In order to achieve a correct forming result it is important to have a smooth strip entry into the forming cage.

process Copra ® FEA RF 2009. Copra FEA RF helps the manufacturer to understand the rollform process, trace reccurring problems and carry out target-oriented optimisation. Due to the fact that rollform technology is continually developing, data M sees it as essential to add new possibilities into the FEA software. The company believes that this new version has come closer to reality than any other simulation or analysis software. The company has enhanced both the FE Analysis software and also the renowned design package Copra RF. One specific feature to have been improved is the handling of cage forming methods. Copra CageForming is a straight forming method that enables the possibility to design and model any type of rolling cage. A cage forming system is a continuous forming process by groups (beams) of single simple rolls and additional supporting outer and inner roll tools. Copra allows for a modelling of various types of straight edge forming systems due

from 3″ to 26″ diameter. The company currently has many international projects in industries including oil and gas, automotive, and construction. Website : www.btwcorp.com

Therefore it is important to optimise both entry passes as well as the position of forming and guiding rolls in the forming line. There are some obvious advantages to perform a mill setup on the computer rather than on the mill by practical trials. These include the possibility to add, edit  Copra RF now also supports integrated drawing dies.
