    CNC turning

    Safe and reliable with perfect virtual simulation

    You can create the CNC programs for your lathes in the complete digital Tebis manufacturing environment to quickly and reliably manufacture simple or complex components. The models of the blankworkpiece  and tool assembly on which every calculation is based – from the cutter to the tool holder – provide you with more reliable collision-checked CNC programs. Your lathes can be in continuous operation, because the CNC programs aren’t generated in the NC control. The right CAD/CAM strategy therefore gives you the full benefit of the especially high material removal rate in turning.

    Time savings
    Shorter programming and manufacturing time
    Process reliability
    Maximum reliability through collision avoidance, even in the programming stage
    Effective strategies for roughing, finishing and downward machining with controllable chip formation and minimal positioning
    High degree of automation thanks to flexible templates; also for machine units and control properties


    Turning: Spiral mandrel

    This video shows the turning of a complex spiral mandrel in tool steel. Many roughing, finishing and downward machining operations can be programmed quickly and easily with collision checking so that the machine can work effectively. Here we’re using a milling/turning machine, because extensive milling and drilling operations are also required to complete the component.

    Comprehensive strategies for CNC turning

    Tebis has all the necessary functions for longitudinal, planar and contour-parallel CNC turning of contours and grooves and for end-face drilling – including off-center drilling. You can just as easily prepare CNC programs for turning cylindrical, tapered or planar threads. Tebis automatically detects whether areas have to be turned from the inside or outside.

    • Off-center drilling
    • Vertical/side/contour-parallel downward machining
    • Inside turning
    • Side-driven grooving
    • Axis-parallel/contour-parallel turning
    • Thread turning
    • Planar turning
    • Pulling cut
    • Manual programming

    Maximum safety with collision checking

    If an area can’t be completely turned with one tilt direction, you can define multiple tilt directions during CNC programming. Your machines will work nonstop. If there could be a collision between a tool assembly and the part  during CNC turning, Tebis automatically reduces the corresponding areas. This gives you collision-checked CNC programs for turning in the calculation stage.

    Short manufacturing time thanks to optimal tool paths

    You can program positioning movements with the shortest path in CNC turning so that retracts and stepovers require less time. Your processes remain safe because automatic collision checking is also performed. If desired, you can also integrate a finishing cut in roughing that also removes the residual stock cusps between the roughing paths.

    Chip control and full-cut detection

    You can interrupt CNC turning after a freely definable path length so that the chip is broken in time when working with soft and ductile materials like copper and aluminum. This allows you to turn different materials even at very high speeds and maintain the carefully defined cutting dataFull-cut detection in grooving ensures a longer cutter life. You decide what happens if the cutter is in full contact: for example, clearing chips or retracting at feed rate.


    Turning with convenient cutting off of the part

    Parts can be cut off from bar stock with a special function for automated machining on lathes or turning-milling centers. You can quickly and easily define the optimal cutting conditions for feed rate and speed upon material exit. You can easily cut the part off straight and finish its contour at the same time without having to design auxiliary geometry. You can deburr the part and turn the bar side-flat during cutoff. This allows you to immediately manufacture the next part with the bar stock. The cut-off part can be transferred to the second spindle or taken up by the part gripper/catcher – all automatically controlled and reliably simulated.

    Manage machine parameters for NC output

    It’s best to define where in the CNC program machine components like clamping elementstailstocks with quills or steady rests will open or close during CNC programming. This saves you time-consuming adjustments on the machine. This is controlled in the Tebis Job Manager in the same way as the entire CNC automation for turning with templates.

    Material tracking for manufacturing progress and simulation

    Tebis uses a blank model to determine the location of the material to be machined during CNC turning. With material tracking activated, this blank is updated in real time following each cut. This allows you to visually follow the manufacturing progress at all times and realistically simulate all turning operations.

    We want to control the machine

    This is a principle that Tebis has followed for more than a decade, and Reiner Schmid, Tebis AG’s head of Product Management, still views it as a unique approach. In an interview with Christopher Detke from NCFertigung, he explains what makes a good CAM system, where the challenges lie and what machines he currently regards as the most complex.

    CNC programming

    Tebis CNC programming greatly reduces programming and setup time in the overall process chain. Tebis combines speed, reliability and a high degree of automation with the greatest possible flexibility. The portfolio includes industry-specific solutions for all areas, including 2.5D, 3D and 5-axis machining.

    CNC automation
    Tebis Automill® evaluates the digital CAD part model and accesses a previously stored structure of digital representations of the company's manufacturing environment and the manufacturing knowledge stored in templates to calculate the NC programs.

    With Tebis, you can provide NC programs to machines with turning, milling and drilling functions. The operation of turn-milling machines with the least possible user intervention and monitoring poses special requirements for the CAD/CAM process.

    In-process measurement

    Establish the necessary process reliability during unattended late shifts and night shifts with automatic checking and correction of part orientation and blank dimensions. This lets you make the best possible use of highly automated machine centers.
