Hexagon Manufacturing Intelligence has upgraded its VISI CAD/CAM software, enhancing the mould and progressive die design processes, along with improvements to the Reverse module.
Designed for the mould and die market, VISI 2020.0 features a new unfolding technology, giving users the ability to work directly on the original solid part without needing to extract the model’s skin. The sheet metal part recognition, meanwhile, now provides an improved graphical representation of the part analysed, by identifying bends, planar faces and features.
Enhancements to the Reverse module provide new functionalities for both reverse and casting processes, giving greater flexibility for both processes. Features such as clipping plane management for point scanning, planar face and draft analysis on mesh data, adapting a mesh to a boundary, and best fit, improve the reverse process from point scanning to solid model generation, and manufacturing.
The software’s new Compare feature lets user compare two entities, such as a point cloud, mesh, or solid, by checking the relative distance. The graphical results show different colours in reference to the distance ranges. Also, additional Meusburger Mould Tool templates (FB, FM and FW types) are now incorporated. VISI’s Flow Analysis has been improved by a new mesh group technology specifically designed for FEM analysis. The flow lines in VISI 2020.0 can now be shown, highlighting possible ‘hesitations’ of the filling from isochrones.
With thermal analysis becoming increasingly more important in optimising mould cooling, the Flow Thermal function has been enhanced by improved coolant flow rate suggestions, giving an indicative value for a single cooling circuit, and an improved solid mesh definition for the mould cavity block, along with each axis, to offer more accurate results.
With the new direct interface between VISI and MSC Software’s Digimat, data showing material local rigidity can be exported into Digimat for the structural FEM analysis process.
