Abstract

PARA PERMITIR UNA INTERPOLACION UNITARIA CON CAPACIDAD DE ACTUACION EN TIEMPO REAL, SE EJECUTA LOS SIGUIENTES PASOS: 1.1 LA INFORMACION A TRAVES DE LAS PISTAS GENERADORAS SE EXTRAE CON REFERENCIA AL SISTEMA DE COORDENADAS DE LA PIEZA DE TRABAJO DE UNA FUENTE (CAD/CAM) EN FORMA DE NURBS, TAMBIEN SEGUN POLINOMIOS RACIONALES O EN DISPOSICIONES DE BASES -RACIONALESNO UNIFORMES, 1.2 EN EL CONTROL (NC) NUMERICO SE TRANSFORMAN LAS APLICACIONES NURBS EN POLINOMIOS RACIONALES O SON ACEPTADAS DIRECTAMENTE MEDIANTE POLINOMIOS RACIONALES YA PRESENTES, 1.3 ESTOS POLINOMIOS TRANSFORMADOS O RACIONALES TRANSFORMADOS SE TRANSFORMAN BAJO CONSIDERACION SEGUN SEA NECESARIO DE LAS DIMENSIONES DE CORRECCION, EN PARTICULAR EN LAS CORRECCIONES DE HERRAMIENTA, DE FORMA ANALITICA EN UN SISTEMA DE COORDENADAS BASICO, DONDE LAS PISTAS SE ENCUENTRAN PRESENTES COMO CURVAS EN FORMA DE POLINOMIOS TRANSFORMADOS. 1.4 SE CONSIGUE UNA INTERPOLACION DE ESTOS POLINOMIOS TRANSFORMADOS DESPUES DE UN PROCESO DE INTERPOLACION UNITARIO, 1.5 LA SEÑAL INTERPOLADA SE TRANSFORMA EN EL SISTEMA DE COORDENADAS DE MAQUINAS Y SE DISTRIBUYE A LOS EJES DE MAQUINAS INDIVIDUALES, GUIANDOSE A LOS ACCIONAMIENTOS (A, B, C) COORDINADOS.
