2.5D Machining: Milling, Drilling

    Typical 2.5D drilling and milling tasks can be programmed particularly efficiently using hyperMILL® CAM software.

    2.5D Machining | Milling Drilling

    hyperMILL® 2.5D machining is typically used for plate processing in tool and mould manufacturing. Numerous pockets, plane levels, contours and drill holes present very special challenges here. Intelligent mechanisms, such as the recognition of pocket features, help the CAM user to program significantly faster.
    With its high-performance cutting functions (HPC), hyperMILL® MAXX Machining is able to give an additional boast to performance during 2.5D roughing.

    Accelerated 2.5D programming

    2D components normally offer great potential for automation. hyperMILL® therefore provides a comprehensive solution that allows programming to be completely automated. All 2.5D strategies can also be applied to multi-axis machining.

    Details on 2.5D milling

    Pocket Milling

    For the machining of straight and inclined pockets with any contour, including the automatic recognition of islands and rest material areas. Open and closed pockets can also be machined without any problems using the ‘Pocket Milling’ strategy.

    Contour Milling

    Optimised machining of open and closed contours with the option of path compensation, automatic rest material detection and the machining of undercut contours that are difficult to access. The ‘Contour Milling on 3D Model’ strategy also includes:

    • Collision check for the 3D model
    • Automatic contour optimisation and sorting
    • Trimming of toolpaths to stock or model
    • Automatic approach and retract strategies

    Trimming the toolpath against the model

    Rest Machining

    During 2.5D contour and pocket machining, some areas cannot be machined with larger tools. The rest material strategy detects these component geometries and calculates separate toolpaths for them with smaller milling tools.

    Plunge Milling

    The 2D curve-based Plunge Milling cycle allows the efficient roughing and finishing of vertical contours, even in material that is difficult to cut.

    5-axis multi-axis indexing

    All 2.5D machining strategies can also be applied for multi-axis indexing with a fixed tool angle. During this process, the machining orientation is defined using the frame. Simple frame definition and management assist the user in programming machining operations with tilted fourth and fifth axes. With transformations in the NC programs, users can easily and conveniently create programs for multiple components clamped within a single plane or in a tombstone fixture, for instance. All traverse movements are checked for collisions and path-optimised.
