OPEN MIND Technologies AG, one of the leading CAD/CAM software developers, is set to present at the 20th EuroMold trade fair at the trade fair grounds in Frankfurt, Germany, from 3 to 6 December 2013. Everything at Stand 8.0 L07 will revolve around machining strategies in the hyperMILL® 2013 CAM software and the hyperMAXX® high-performance cutting module. The hyperCAD®-S CAD software, which is specially geared towards the requirements of CAM users, will also form part of OPEN MIND's exhibition.

Tool and mould manufacturers are familiar with typical challenges in machining. OPEN MIND has implemented machining strategies in hyperMILL® 2013 that address these challenges. For example, the software developer developed the new 'Rib Milling' cycle together with one of the largest German automotive manufacturers. This is good news for tool makers who need to mill deep, narrow cavities for ribs in their moulds. The cycle automatically detects grooves that have to be milled. Steep areas and floors are machined separately. Depending on the workpiece geometry, the system selects a suitable roughing strategy, and contiguous areas are completely machined.

An additional highlight of hyperMILL® 2013 is its extension for '5axis contour offset finishing': Barrel cutters can now be used here. This strategy uses the large effective radius of the barrel cutter with a point milling contact style. This allows increased step-over distances between passes for free-form surfaces.

Harmonic movements during roughing

hyperMAXX®, the roughing module fully integrated into hyperMILL®, combines optimal milling paths, maximum material removal and the shortest possible machining times. Ideally distributed milling paths and the dynamic feedrate adjustment to existing cutting conditions ensure that milling always takes place at the fastest possible feedrate. Machining is always performed using climb milling, in a spiral retraction of tool movements that increasingly approximate the required contour as they reach the end. The hyperMAXX® tool path is calculated with regard to the chip volume, machine data, the material to be cut and balanced movement.

CAD for CAM users

The architecture, core, graphics, database, user interface and API for hyperCAD®-S have been redeveloped. The software is perfect for imported data. Users have the advantage of being able to easily modify any of the geometry elements at any time. Curves and free-form surfaces are depicted using Bezier and NURBS geometries. In addition to the familiar basic elements for construction, the core now also provides a number of elements that specifically aid CAM programmers, including tool paths, polygon networks, point clouds and a rectangle element.
