<p>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.
