Feasibility Study of the Method Choice of Manufacturing Screw Cleaning Elements with the Development and Use of Software

computer simulation of a curved profile formation on a helical spiral was carried out. A feasibility study was conducted in order to choose the method suitable for manufacturing of L-shaped helical spirals using specially developed software for calculating of the costs of helical spiral formation processes. The tables presenting technological characteristics of the design parameters of screw coiling working bodies manufactured by different methods are provided. The production costs for 1 meter of helical spiral with a curved profile manufactured by different methods are calculated. Theoretical and experimental investigations proved that the most cost-effective method of L-shaped helical spiral manufacturing is to coil it along the inner face from rectangular pieces with simultaneous or subsequent shelve formation.
