Abstract

EN UNA REALIZACION, LA INVENCION DESCRIBE UN TORNO Y UN METODO PARA FABRICAR UNA PRODUCTO CON UNA FORMA QUE NO TENGA SIMETRIA AXIAL A PARTIR DE UNA PIEZA DE TRABAJO, TALES COMO UNA LENTE DE CONTACTO TORICA, QUE COMPRENDE UN EJE PARA HACER GIRAR LA PIEZA DE TRABAJO ALREDEDOR DE UN EJE DE ROTACION, UNA HERRAMIENTA DE CORTE, UN SOPORTE BIAXIAL PARA SUJETAR LA HERRAMIENTA DE CORTE Y PARA MOVER LA HERRAMIENTA DE CORTE A LO LARGO DE UNA TRAYECTORIA PREDETERMINADA ADYACENTE A LA PIEZA DE TRABAJO CUANDO EL EJE HACE GIRAR LA PIEZA DE TRABAJO Y UN MECANISMO PARA HACER OSCILAR LA HERRAMIENTA DE CORTE A LO LARGO DE UN EJE DE OSCILACION CUANDO EL SOPORTE BIAXIAL MUEVE LA HERRAMIENTA DE CORTE A LO LARGO DE LA TRAYECTORIA PREDETERMINADA, ESTANDO EL EJE DE OSCILACION ORIENTADO EN UN ANGULO NO NULO CON RESPECTO AL EJE DE ROTACION. PREFERIBLEMENTE, EL ANGULO NO NULO ES, APROXIMADAMENTE, DE 45 (GRADOS) . EN UNA SEGUNDA REALIZACION, EL TORNO COMPRENDE UN SOPORTE GIRATORIO PARA MOVER EN FORMA DE ARCO CIRCULAR UNA HERRAMIENTA DE CORTE ADYACENTE A LA PIEZA DE TRABAJO Y UN MECANISMO PARA PRODUCIR UN MOVIMIENTO DE VAIVEN EN FORMA TRASLACIONAL DE LA HERRAMIENTA DE CORTE CUANDO LA HERRAMIENTA DE CORTE SE MUEVE EN ARCO ADYACENTE A LA PIEZA DE TRABAJO.
