Abstract

Se provee un inserto cortador (209, para uso en una herramienta denominada molino rotatorio (10). El inserto cortador (20) incluye un cuerpo de inserto comprendiendo una cara inferior (22), una cara superior (24) y una cara lateral (26). Un borde cortador escalonado (30) esta formado en la interseccion de la cara superior (24) y la cara lateral (26) para atacar una pieza de trabajo y remover un recorte de éste. El borde cortador escalonado incluye al menos dos porciones de borde desniveladas (30a-c) que producen segmentos de recortes diferentes, transversalmente espaciados, durante la operacion de cortado. Las porciones de borde desniveladas (30a-c) están conectadas por porciones de borde de transicion (30d-e) que están dispuestas en un ángulo obtuso con respecto a las porciones de borde desniveladas. El ángulo de las porciones de borde de transicion tienden a diseminar los segmentos de recorte individuales separados durante la operacion de maquinado para causar un efecto de adelgazamiento de los recortes entre los segmentos de recorte individuales. Todo y todos los bordes cortadores están helicoidalmente curvados de tal manera que los bordes de corte se encuentran en la superficie de un cilindro circunscrito definido por la rotacion de los bordes de corte alrededor del eje de un molino cortador.
