... of polyvinyl chloride (PVC) were exposed to the impact of abrasives while rotating at high speed within a fluidization column. The interaction between the Al 2 O 3 abrasive media and the PVC surfaces was studied to identify the effect of the main process parameters, such as the machining time, the abrasive...

...P. J. Borkowski; J. A. Borkowski Novel method for the 3D shaping of different materials using a high-pressure abrasive water jet is presented in the paper. For the steering movement process of the jet, a principle similar to the raster image way of record and readout was used. However, respective...
