Abstract
The concept of coupling manufacturing chain simulations is applied in the manufacturing chain of casting - heat treatment- cutting. During the virtual reality data processing, methods for data reduction were used in order to achieve interactive refresh rates. Therefore the number of polygons of the surface mesh was reduced and part areas from the total data record were selected. A local refinement of the heat treatment simulation was accomplished, whereby the difference of the resolution of the mesh by heat treatment and machine cutting could be reduced of initially 20 to 6. The virtual reality data processing was compared with a conventional post processing (the comparison of simulations with and without material history). It h that residual stresses affect the cutting simulation result. It also turned out that virtual reality offers an advantage for the processing of complex simulation data, as regarded in this work. In particular the connection of virtual reality an comparative visualization was regarded as a good combination.
