Abstract

UNA MAQUINA PORTAHERRAMIENTAS TIENE UN CARRO (28), UN CARRO PORTAPIEZAS (28), UN CARRO PORTAPIEZAS (28) PARA DESPLAZAR UNA PIEZA DE TRABAJO (32) DE LA CUAL SE QUITA MATERIAL MEDIANTE UN UTIL (54) SUSTENTADO POR UN CARRO PORTAUTILES (48). UNA ESCALA DE DOS EJES (86, 88) ESTA ACOPLADA A UNO DE LOS CARROS, Y COLABORA CON UN CABEZAL LECTOR (96, 98) FIJADO AL OTRO CARRO. LA SALIDA DEL CABEZAL DE LECTURA ES PROCESADA POR MEDIOS DE PROCESAMIENTO DE SEÑALES PARA PROPORCIONAR UNA INDICACION DE LA POSICION Y/O MOVIMIENTO DE LOS CARROS UNO CON RESPECTO AL OTRO PARA GENERAR DATOS DE POSICION SOBRE UNO O AMBOS CARROS PARA AYUDAR A CONTROLAR SU MOVIMIENTO CON EL FIN DE REALIZAR UNA OPERACION DE MECANIZADO. MIDIENDO DIRECTAMENTE LAS POSICIONES RELATIVAS DE LOS DOS CARROS, AL MENOS SE MITIGAN LOS PROBLEMAS DERIVADOS, POR EJEMPLO, DE LAS DISTORSIONES DEL BASTIDOR DE LA MAQUINA SOBRE EL CUAL VAN MONTADO LOS CARROS. UNA REALIZACION PREFERIDA DE LA MAQUINA TIENE UN SEGUNDO CABEZAL DE LECTURA ACOPLADO A UN CARRO QUE TIENE LA ESCALA EN OTRO CARRO DE MANERA QUE LAS SEÑALES DE SALIDA DE LOS DOS CABEZALES DE LECTURA PUEDEN UTILIZARSE PARA DETERMINAR SI SE HA PRODUCIDO ALGUN DESPLAZAMIENTO ANGULAR DE LOS RECORRIDOS SEGUIDOS POR LOS CARROS. TAMBIEN SE DESCRIBE UN PROCEDIMIENTO PARA DETERMINAR EL MOVIMIENTO LINEAL DE UNO DE LOS CARROS CON RESPECTO A OTRO, Y EL PROCESO DE MECANIZADO LOGRADO UTILIZANDO LA MAQUINA HERRAMIENTA.
