3D milling for roughing and finishing

    The reliable and efficient path to premium surfaces

    The 3D milling strategies for roughing, finishing and for residual stock machining let you prevent collisions right from the start. The wide range of collision avoidance solutions are optimized for specific situations. For example, depending on the application the tool automatically avoids collisions or areas at risk are reduced. In combination with precise simulation technologies and harmonic slope-adjusted NC paths, optimal traverse paths are created for the machine axes in 3D milling. Machining time is reduced to a minimum. Of course, functions for 5-axis simultaneous milling in the release direction and for 3+2-axis milling with the positioned axes are also provided in Tebis.

    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 the update 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 subdivided in slope ranges that can each be machined using special strategies and tools – the best prerequisite for automated NC programming in combination 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 fit your machine control.

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

    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.

    3+2-axis multi-sided machining

    Use key and ball cutters in multi-sided machining of undercut areas and achieve a very high surface quality with the shortest possible tools. The part can be completely machined in a single setup. This type of machining is also suitable for simultaneous 5-axis milling of undercut pockets and penetrations as well as for flow channels and impellers.

    Another advantage: The tilt direction can always be adjusted interactively, enabling you to remain flexible despite the high degree of automation.

    3+2-axis milling programs can be easily generated in Tebis: The procedure is always the same whether programming 3-axis or 3+2-axis programs. Another advantage: The tilt direction can always be adjusted interactively, enabling you to remain flexible despite the high degree of automation.
