RESEARCH ON THE INFLUENCE OF LUBRICATION ON THE RESULTS OF THE MICRO-DEEP DRAWING PROCESS USING A FINITE ELEMENT MODEL ON QFORM 10 CLOUD SOFTWARE

Tóm tắt

In the process of material forming, the selection of friction conditions (lubrication) belongs to one of the important tasks affecting, for instance, the value of deformation force. The article deals with the impact of friction factor calculated based on the A.N. Levanov’s friction law on the deformation forces during the micro-drawing process of a cup made from
aluminum alloy AD33 with the help of the finite element modeling in the QForm 10 Cloud. The forming process was simulated for two cases, with and without lubrication, whereby
several scaling factors for toolset and blank were under study. It was found that the maximal force obtained for tools without lubrication, and the influence intensity decreased with a
reduction of the dimensions of the workpiece and toolset.
