    3D milling for roughing and finishing

    The reliable and efficient path to premium surfaces

    The 3D milling strategies can be used to create 3-axis and 3+2-axis NC programs for roughing, finishing and residual stock machining. You can avoid collisions during calculation. For example, the tool automatically avoids collisions or reduces areas at risk, depending on the application. In combination with theprecise simulation technologies and harmonic slope-adjusted NC paths, optimal traverse paths are generated for the machine axes in 3D milling.

    The most important strategies for 3D milling

    • Direct 3D milling on surfaces
    • End-to-end accounting for blanks
    • Roughing in planes, protecting tools
    • Equidistant 3D finishing
    • Precise residual-stock machining with material tracking
    • Part-oriented curve milling
    • Height-sorted fillet machining
    • Automated machining of ribs and slots

    Prevent unnecessary idle travel during roughing

    You can quickly and easily define any blanks. The material can be machined from different tilt directions. This significantly reduces the computational effort. The blank is updated and passed on to the next machining operation – and theupdate is always performed using the actual cutter geometry. The system safely and reliably mills only where there is remaining material. 

    Tebis uses different options for full-cut handling and full-cut avoidance in 3D milling: Depending on the situation, full-cut areas are machined trochoidally, or the path layout is automatically adapted to the geometry without full-cut machining. This is optimal for adaptive roughing with HPC cutters. All path layouts are automatically smoothed, enabling further optimization of feed rate.

    Finishing for best surface quality

    Tebis strategies for optimized 3D stepover ensure uniform stepover on the surface in 3D milling of both flat and steep areas. The part is automatically divided into slope areas that can be manufactured with special strategies and tools – the best prerequisite for automated NC programming in conjunction with Tebis template technology.

    High-quality toolpaths: HSC point distribution optimally positions the NC points on the surface. You can influence the point distribution so that the output toolpaths precisely match your machine control. An additional benefit: You can mill directly on surfaces without needing a faceted substitute model.

    Precisely determine milling areas: In Tebis, the contour of the virtual tool matches exactly with that of the actual tool used. You can therefore optimally use the potential of your HFC cutters even for prefinishing.

    Path and height-oriented residual stock machining

    Depending on the task, special residual stock machining strategies are available for 3D milling, such as for fillets or complex cavities. Path and height-oriented NC programs reduce machine run times. You also benefit from precise calculation of the milling areas in residual stock machining.

    Machine undercuts in a single setup

    In multi-sided machining of undercut areas, completely machine the component with key and ball cutters in a single setup. You can achieve a very high surface quality using the shortest possible tools.  

    Quickly create collision-checked NC programs

    Tebis detects potential collisions automatically during NC calculation. The wide range of collision avoidance solutions are optimized for specific situations.

    Area reduction accounting for the real head geometry

    In the event of potential collisions with the machine head, milling areas are automatically reduced or excluded from machining. You can increase process reliability and use the shortest possible tools for every job, ensuring optimal cutting conditions.

    The "Programming with virtual machine" license also enables interactive rotation of the head or table about the C axis in the machine kinematics. The benefit is especially clear for asymmetrical heads: The maximum possible material is removed with the selected tool. Unnecessary residual stock is avoided. The interactive rotations are immediately accounted for in the area reduction.

    Significantly more material is removed with the C axis rotated

    5-axis simultaneous avoidance milling

    Collisions of the tool holder with the component in 3+2-axis NC programs can also be avoided with  automated 5-axis simultaneous machining. This enables top-quality machining of electrodes or components with deep cavities using short tools.

    Indexed residual stock programs

    Indexed residual stock programs can also be calculated automatically. This reduces machining times on the machine and achieves better surface quality.

    Great flexibility through interactive interface

    An additional benefit: The tilt direction can be adjusted interactively, enabling you to remain flexible despite the high degree of automation.
