Ability to import all electronic data formats via standard interfaces is a key feature of Open Mind's new Hyperform V5 computer-aided manufacturing (CAM) system, developed specifically for the mould and toolmaking sector. Many data exchange formats are included such as IGES, STEP, DXF and VDA, and there is the option of a direct CATIA interface. Users with a multi-client customer base will therefore have no problem in handling CAD models presented in a variety of formats.
With the introduction of this product, Open Mind is now primarily focused on the mould, tool and die market and is emerging as one of the leaders in the field, according to the US research organisation, CIMdata, in its 1999 industry report.
The privately owned, German company was the fastest-growing cam software vendor in Europe during 1998 and 1999.
Last year, revenues grew by about 35 per cent over the previous year to in excess of US$15 million.
The rationale behind Hyperform is that many toolmakers do not want to provide a design service, choosing instead to import component data in electronic form from its customers.
Graphical exchange is normally required but invariably the models do not translate cleanly.
Toolmakers which find themselves in this position are looking for a powerful, stand-alone cam system married to basic CAD functions for performing limited operations on the imported model, such as surface functionality for closing gaps between surfaces, creation of boundaries and surface trimming.
This minimises the need to shuttle between CAD and CAM when preparing the imported model for machining.
Development of machining programs designed to maximise shop floor productivity is where Hyperform really shows its mettle.
The system satisfies the entire range of requirements from simple 2.5D pocket milling and drilling cycles through to full simultaneous 5-axis work with full collision avoidance.
An interesting aspect of the latter safety feature is that it takes into account both the tool and the toolholder.
Milling strategies available within Hyperform include Z-level roughing and finishing (waterlining), milling along leading curves, slope machining and fully automatic rest machining.
High speed functions include 3D equidistant finishing, HSC loops for finishing applications and automatic pencil milling.
According to the features being machined, the machining strategy can be switched between the overall (global) strategy and a more suitable / productive local strategy within the same program.
Automated calculation of machining areas and minimised tool movements reduce both program generation time and machining time for maximum productivity on simple or complex parts.
HyperFORM-originated tool paths can be viewed using the hyperVIEW simulation package, while post processors are available to suit the majority of CNC systems.
