Abstract

This article provides information about comparative research on designing of spinning trajectories for products with a non-circular cross-section. Generation of two outlines for the two mandrels was carried out using three methods: (1) a spreadsheet, (2) a 2D CAD program, and (3) a 3D CAD program. Technological tests were carried out using mandrels with the following geometries: ellipse and square. The material used in the research was aluminum Al 1050A. Due to the high degree of complexity in the design of the trajectory, Method 1 was used only for spinning of the ellipse. Methods 2 and 3 were used for spinning the square. Only Method 3 was suitable for programming of upsetting moves of tool. Test of Vickers's microhardness was conducted on sample 3. The influence of the spinning trajectory on the drawpiece was evaluated by measuring the percentage reduction of side wall thickness.
