OPTIMIZATION OF CUTTING TOOLS SHAPE FOR TURNING OF RAILWAY WHEELS BY DESIGN STUDIES
The shape of cutting tools is considered to be the optimization criterion by means of computer-aided design, namely the method of design studies in SolidWorks. The block diagram, representing the algorithm of solving the plate geometry optimization problem which reflects design stages is presented. The following plate parameters are used as study variables: the rake angle, the angle of the strengthening bevel and its width. By solving the optimization problem the version of plate geometry was determined which provides the lowest tension in the body of the tool while turning the wheels taking into account temperature and force action.
