Open Mind Technologies Latest version CAM software improves machining
UK – Open Mind has launched the latest release of its CAM software, Hyper-Mill 2014.2, featuring several new functions and enhancements within the existing framework with a second version scheduled to be released this year, the company says.
In addition to a key extension for solid modelling in Hyper-CAD-S, the CAD part of the system, Hyper-Mill 2014.2 features a range of improvements for CAD programmers and machining.
A new function for 3D shape Z-level finishing (image) enables reference curved bottom surfaces (in X and Y coordinates), after which the milling paths are aligned, to result in the milling tool nestling along the boundary edge between the bottom and the wall. All intermediate levels are offsets of the bottom plane, the company explains. Its soft bounding concept integrated into this new function ensures that the boundaries to adjacent surfaces are calculated precisely and that sharp outer edges are machined smoothly. This is said to result in reduced programming and machining times.
Another enhancement is that open, deep, steep and flat areas of cavities can now be machined in one job with collision avoidance, and the resulting rest material areas are transferred automatically to the subsequent job. Tool selection and positioning take place here again, a process repeated until the required contour is achieved.
Upgrades in Hyper-Maxx high-performance cutting (HPC) module are said to include plunging the milling tool into the material around pre-drilled holes to save ‘ramping-in’ of the milling tool at the start of machining. Tools are therefore protected, also when materials are difficult to cut. The machining process is also collision-checked by selecting a zigzag mode. This mode suits machining large workpieces as repositioning movements are saved and machining times shortened.
One more new feature is the 2D plunge milling where material is removed by plunging a milling tool. This is suitable for both roughing and finishing, allowing fast machining and good for materials that are difficult to cut, the company notes.
