A real plus for combined turning/milling operations: In addition to cylindrical parts, tapered parts such as screw conveyors can now also be machined with high efficiency. The tool first roughs the part to the maximum possible depth with a low stepover and large downfeed in a single pass. Then it machines the residual stock from bottom to top with a smaller cutting depth – precisely to the stock allowance. This procedure reduces tool wear and ensures a high material removal rate on the machine. The user can easily program the final finishing operation with a special function: Only the strategy is replaced – the system does the rest.
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 on material exit. You can easily cut the part off straight or finish its contour at the same time without having to design an 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 – with automatic control and reliable simulation.
This innovation is especially advantageous for manufacturing companies that rely on combined turning/milling operations, especially if the components to be machined have a high milling fraction: Tebis can now be used to program toolpaths for sequential processing on machines with multiple tool and component holders. The individual steps – such as milling with a milling head or turret, stabilizing with a centering tip or clamping with a sub spindle – can be combined in any way. All tool and component holders are stored in the virtual Tebis process libraries: These can be interchanged quickly and flexibly in programming. As always in Tebis, all system components are fully accounted for in collision checking and simulation. Programming is as easy as can be, following Tebis's stringent and proven programming logic. Tebis automatically generates NC code for any machines and supports all control-specific program structures, such as Gildemeister structure programs.
