Abstract

SE DESCRIBEN UN TORNO Y UN METODO DE UTILIZACION DEL TORNO PARA FORMAR UNA SUPERFICIE ASFERICA SOBRE UNA PIEZA DE TRABAJO, EN DONDE LA PIEZA DE TRABAJO SE INSTALA SOBRE UN SOPORTE QUE TRANSPORTA ROTATORIAMENTE UN HUSO, CABEZAL Y BANCADA DE UN TORNO, CON TAL HUSO Y PIEZA DE TRABAJO, GIRANDO ALREDEDOR DEL EJE DEL HUSO, CON LA PIEZA DE TRABAJO ESTANDO ACOPLADA MEDIANTE UNA HERRAMIENTA DE DAR FORMA, CUYA HERRAMIENTA DE FORMACION SE DESPLAZA A TRAVES DE UN PASO EN CURVA ALREDEDOR DE UN EJE QUE ESTA POR LO GENERAL TRANSVERSAL AL EJE DEL HUSO. EL METODO Y EL APARATO PROPORCIONAN ADEMAS LA DETERMINACION DE LA POSICION ANGULAR VARIABLE CON EL TIEMPO DE LA HERRAMIENTA DE FORMACION A LO LARGO DEL PASO EN CURVA, PARA DETERMINAR LA POSICION ANGULAR VARIABLE CON EL TIEMPO DE UN PUNTO DE LA PIEZA DE TRABAJO ALREDEDOR DEL EJE DEL HUSO, Y PARA ALTERNAR EL SOPORTE DE LA PIEZA DE TRABAJO Y LA PIEZA DE TRABAJO SOSTENIDA ASI RESPECTO AL CABEZAL DEL TORNO, Y RESPECTO A LA HERRAMIENTA DE FORMACION, EN SINCRONIZACION CON EL MOVIMIENTO DE LA HERRAMIENTA DE FORMACION Y CON LA ROTACION DE LA PIEZA DE TRABAJO ALREDEDOR DEL EJE DEL HUSO, PARA FORMAR LA SUPERFICIE CURVA DESEADA. RELACIONES ESPECIFICAS SE DAN PARA EL DESPLAZAMIENTO DEL SOPORTE DE LA PIEZA DE TRABAJO A LO LARGO DEL EJE DEL HUSO EN RELACION RESPECTO AL ANGULO DE ROTACION DE LA PIEZA DE TRABAJO ALREDEDOR DE SU EJE, EL MOVIMIENTO DE LA HERRAMIENTA DE FORMACION Y LOS RADIOS DE CURVATURA DESEADA.
