Computer Modeling of a Pump Screw and Disc Tool Cross Shaping Process

The article describes the method of computer contouring of disc tools for pump screws and compressor units treatment. The described method is based on the usage of mathematical kernel and software of a modern graphical CAD system. The method does not require to use mathematical models for solving the contouring problem under consideration. Hence this does not call for the usage of the characteristic numerical computation methods. Moreover, the proposed method allows the visualization of the screw and tool shaping surfaces physical interaction and the optimization of the contouring process at the visualization level.
