Abstract

Se provee un inserto para usarse en una fresa con punta de bola (1), que incluye un cuerpo de inserto (22) teniendo una pared superior (24), una pared de fondo (28), y al menos una pared lateral arqueada (30). Se define un filo cortante arqueado (34) en la interseccion entre las paredes superior y laterales, que incluye una pluralidad de ondulaciones sinusoidales (36) para las fuerzas de corte, y la vibracion, y mejorar la rotura y remocion de virutas removidas de una pieza de trabajo (66) durante una operacion de corte. Una porcion final del inserto (67) cruza el eje de rotacion (A) cuando se monta el inserto en el asiento del cuerpo extremo de fresa (3), y las ondulaciones (36) reducen las considerables fuerzas cortantes aplicadas al filo cortante (34) en este lugar. EL filo cortante tiene un perfil que sigue el contorno de una esfera para permitir el maquinado de un corte redondo. La pared lateral del cuerpo del inserto incluye una porcion de relevo superior (44) dispuesta directamente bajo el filo cortante, con un ángulo de alivio para permitir a las ondulaciones de realizar estrías indeseadas o marcas en las paredes del corte redondeado.
