Adaptive pocket feature allows for automatic programming of rectangular pockets.
hyperMILL offers new strategies for impellers and blisks.
OPEN MIND's hyperMILL 2012 features innovations such as automatic programming options for rectangular pockets, optimizations for 3D roughing and enhanced strategies for 5-axis machining.
hyperMILL 2012's "adaptive pocket" machining mode allows for automatic programming of rectangular pockets. Within a machining job, 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, hyperMILL automatically selects the most suitable machining method: spiral, contour-parallel or peeling. Optimized clearing movements take place in long, straight paths with constant cutting conditions. Critical full-cutting areas are parameterized separately, allowing control over feedrate values and reduced production times.
During 5-axis shape offset machining with hyperMILL, users now avoid redundant movements due to the axial sorting option that makes it possible to divide machining by area. This allows corners or pockets, for example, to be machined individually one after another. The user can decide whether to create toolpaths with offset level sorting or axial sorting.
There are several new features for roughing in the 5-axis impeller and blisk package. For impellers, it is now possible to divide the machining region into a left and right pocket between the main blade and the splitter. This option means 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.
hyperMILL 2012 supports tapered tools for 3D ISO machining, including automatic collision avoidance. In the process, the entire tool is checked for collisions against the model to help provide high process reliability. According to the company, tapered tools offer more stability, reduce tool vibrations and improve surfaces simultaneously.
For turning operations, hyperMILL functionality has been extended to include inclined grooving. This is also why offset tools can now 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 company reported that, due to the continuous inward movement of the ramp, the tool path is optimized and zig-zag movements are avoided.
