Video: Hybrid Production Of Functionally Integrated Plastic Products
In a manufacturing cell, the IKV researchers show the automatic, sequential production of different demonstrator components without manual intervention from the CAM file to shipping. The various processes required for this are digitally and physically networked in a system. The CAD data are generated via the associated pre-processing. This hybrid system takes over the advantages of the manufacturing processes used, such as high dimensional accuracy using subtractive manufacturing and the high degree of design freedom of additive manufacturing. The order-oriented single-part production of "batch size 1" components can also be realized. To this end, the innovative process implements a sequential change between the individual manufacturing processes.On the other hand, all current challenges and previous disadvantages of additive manufacturing with regard to dimensional accuracy, tolerated surfaces, integration of insert parts and multi-material integration are completely avoided. So the degrees of freedom of additive manufacturing are not restricted by other manufacturing processes, such as. B. the processing of complex undercuts, canceled.
The IKV researchers use a drive unit with an automatic tool change system to implement the coupling technology. Using a standardized coupling, different tools can be used flexibly and use the kinematic power of the drive unit. Tools such as screw extruders, conventional fused layer modeling (FLM) extruders, milling cutter holders and grippers are used. Mass and fluid flows and electrical signals can be transmitted via additional coupling elements and the energy supply of the respective tools can be ensured.
In addition to exploiting the automation potential, the plastics technology focus is on the use of a screw-based extruder for the application of small melt volumes. On the one hand, this means that standard materials can be processed in granulate form, and on the other hand, the high pressure in the nozzle antechamber offers the possibility for the first time of processing highly filled thermoplastics in additive manufacturing. This enables mechanical properties to be increased and the potential for shrinkage and resulting warpage to be minimized. (qui)
