Máquina CNC de 7 ejes para cortar poliestireno expandido (EPS) obteniendo superficies de doble curvatura en una sola pasada

7-axis CNC machine to cut expanded polystyrene (EPS) for obtaining double-curved surfaces in a single pass

Zapata, Francisco Javier Quitral ; Böhme, Luis Felipe González ;

Artigo Completo:

We present a novel CAD/CAM apparatus and method for single-pass cutting of double-curved expanded polystyrene formworks. A rationalization approach was implemented using generic solvers in a popular free visual programming environment integrated into a well-known commercial CAD software, which allows finding elastica curve sections for processing double-curved NURBS surfaces. This procedure allows us to convert bending curves geometry into G-code coordinates for numerically controlling a flexible cutting hot-blade. A prototype 7-axis machine was experimentally validated in a series of cutting processes of EPS formworks to build a double-curved concrete pony wall.
