OpenMind HyperMill CAM now features 'adaptive pocket’ machining mode

OpenMind Technologies' September 2012 release of its HyperMill CAM solution features an 'adaptive pocket' machining mode that allows automatic programming of rectangular pockets, so that a classification occurs automatically in closed and open pockets and rectangular levels. According to the various accessibility conditions for the tool and relative sizes of the tool and pocket, the software automatically selects the most suitable machining method, whether it is spiral, contour-parallel or peeling.

The optimised clearing movements take place in long, straight paths with constant cutting conditions. Critical full cutting areas are parameterised separately, allowing control over feedrate values and reduced production times. Time-saving 5-axis strategies in hyperMill 2012 will also include an axial sorting option for shape offset machining to avoid redundant movements. This makes it possible to divide machining by area. It allows corners or pockets to be machined individually one after another. The user can decide whether to create toolpaths with offset level sorting or axial sorting. Several features for roughing have been added in the 5-axis impeller and blisk package. For machining of impellers, it is now possible to divide the machining region into a left and right pocket between the main blade and the splitter. This means that these areas can now be machined with different tools in a targeted manner. The flank mode during roughing enables swarf cutting near blade surfaces. The user can decide whether to use the swarf mode for every step or just for the last step. This extension results in a consistent stock allowance for finishing. Production time can also be reduced here as preliminary finishing can be skipped, explains OpenMind HyperMill 2012 will now supports tapered tools for 3D ISO machining while including automatic collision avoidance. In the process, the entire tool is checked for collisions against the model, which ensures high process reliability. Tapered tools offer more stability, reduce tool vibrations and improve surfaces simultaneously. For turning operations, functionality has been extended to include inclined grooving. This is why offset tools can now also be used. The tool database has therefore been expanded to include these recessing tools. Pocket milling has been improved in the 3D roughing area. As a result, for the machining of pockets, the ramp is moved continuously in one direction. The pocket is then cleared from the outside in. The advantage with the continuous inward movement of the ramp is that the toolpath is optimised and zigzag movements are avoided.
