Although the previous version of hyperMILL featured high-precision profile finishing, version 2019.2 offers a comparable function for 3D shape Z-level finishing. The ‘high-precision surface mode’ option ensures smooth surfaces with tolerances in the micron range. This functionality saves time on post-machining finishing processes, particularly when applied to mould making. The ‘smooth overlap’ function has the same effect for 3D profile finishing.
In hyperMILL 2019.2, the hyperCAD-S ‘global fitting’ function is directly integrated into the CAM strategy (in 5-axis tangent machining). With this feature, multiple faces can be joined into one face with defined ISO orientation. The principle of using CAD elements for CAM programming is also applied, for example, for automatic face extension. With the automatic face extension, bounding surfaces are automatically extended during programming to improve the edges of machined surfaces. This function simplifies programming since these adjustments are made within the CAM strategy, without switching to the CAD environment.
In the previous version of hyperMILL MAXX Machining, turn-roughing was implemented with trochoidal tool paths. Optimised connecting paths and fluent machine movements ensure high-performance machining, which means significantly higher machining values can be driven compared with conventional roughing methods. Version 2019.2 guarantees even greater process reliability for high-performance turning, while tool-life monitoring makes it possible to restrict the use of a cutter by the distance covered, the number of toolpaths, or a time limit. If the defined limit is reached, a retract macro is generated automatically and the job ends.
Open Mind has also further improved the feature and macro technology in the latest version to enable more secure and simpler programming for users. One function that is generally useful for everyday work is the definition of macros for recurring geometries. Open Mind has added full-text searching to the macro database. Users can also define machine and material groups as defaults to make it easier to select macros.
Hole-feature linking means that model changes made to CAD features are automatically transferred to hyperMILL. Since design changes in CAD are associatively linked with the CAM system, users can quickly and securely make updates.
An important aspect of automating CNC programming is analysing the existing design in terms of possible machining strategies. Here, an interesting function is now available for users who work with very large parts in hyperCAD-S. The function enables the workpiece mass and centre of mass to be calculated with a material definition for solid, mesh and stock models. Another highlight of the CAD portion of the suite is the ‘undercut’ function, which makes it possible to detect undercut areas on components quickly and reliably. Moreover, the new ‘local curvature’ analysis function makes it possible to detect curvature radii on components.
