This paper presents the design of a machine using for incremental sheet forming (ISF) technology. Mechanical design has differences compared with conventional CNC machine which has enough rigidity to match the high value of axial force when processing by ISF technology. The machine is manufactured successfully and operates stably when forming steel sheet of 210mm square and thickness of 1.5mm. It shows that the control and mechanical design presented shows appropriate and capable of manufacturing a machine with larger machining size to use for the actual sheet products in industries.
The article exposes contemporary materials and structures for metallurgy. Feasible increase of dynamic forces on the rolling machinery during rolling of billets with masses up to 20 t (Stand No.1 of CWM 1700 HR, «U.S. Steel Košice», Košice, Slovakia, and PJSC «Illich MMPP», Mariupol, Ukraine) is discussed. It is proved that weight of billet, velocities of metal delivery to working rolls and rolling significantly influence the dynamic loads during metal biting. The technical solutions are suggested which would allow the steady rolling process of billets with masses up to 20 t and prevent accidental failures of frame parts, chocks and main lines.
