CAD/CAM High-performance strategies for roughing, drilling and finishing

| Author / Editor: Peter Klingauf / Barbara Schulz

Germany – In order to remain competitive, companies have to produce workpieces more and more quickly, while still maintaining maximum levels of precision and surface quality. Open Mind has released a machining performance package that is said to provide machining time savings of up to 90%.

The ultimate aim of machining is to get as many workpieces as possible out of the machine as quickly as possible. After all, a machine can only earn you money when it’s hard at work. In addition to the choice of machine, the number of workpieces produced is also crucially affected by the CAM system used to implement the optimum manufacturing procedure.

This truth has been emphasised once more by the Hypermill 2016.1 CAM release from Open Mind. A key feature is the Hypermill Maxx machining performance package. It comprises three separate modules for roughing, finishing and drilling, each of which employs different high-efficiency strategies to achieve boosts in productivity.

Open Mind's 5-axis tangent plane machining strategy can substantially increase productivity. In order to allow optimum use of this finishing technique, Open Mind has conceived a special milling tool: the conical barrel cutter. The new cutter geometry has radii of 1,000 mm and more, allowing enormous step-over increments during finishing. This cuts machining times by 70-90% compared to processes that use traditional ball mills.
