Abstract

GARCIA-BARBOSA, Jorge-Andrés; ARROYO-OSORIO, José-Manuel  and  CORDOBA-NIETO, Ernesto. Milling process planning of a complex workpiece using a virtual machine tool. Ingeniería Mecánica [online]. 2014, vol.17, n.3, pp.281-287. ISSN 1815-5944.

We designed and successfully manufactured a complex experimental piece composed of surfaces with zero, positive and negative curvatures. We planned and executed the machining manufacturing process by using milling process with end ball nosetools on a vertical machining center equippedwith a fourth external rotational axis. For planning, simulation and verification of the machining process,we developed a virtual model of the machine tool and its accessories in a commercial system for computer aided machining. By mounting the virtual manufacturing system, we verified the process and adjusted it until observe a good performance. We tested and confirmed the advantages of using the recent virtual methods for simulation and verification of the processoffered by various computer-aided machining systems, especially when dealing with complex processing components in machine tools withmore than three axes.

Keywords : virtual machine tool; process planning; complex parts machining; processes simulation and verification; multi-axis machining.
