Abstract

<B>"PASTILHA INDEXáVEL DE CORTE EM FRESA DE TOPO"<D> A presente invenção se refere a uma pastilha de corte que compreende uma superfície superior de cavaco (16), uma superfície de base (17) e faces laterais (18, 19) entre as mesmas. Em cada uma das faces de extremidade, a pastilha de corte apresenta porções que projetam axialmente (22, 23), cada qual com uma face chanfrada (26, 27). São fornecidas bordas de corte principais na interseção entre a superfície do cavaco (16) e as superfícies laterais (18, 19). Em cada superfície lateral é fornecida uma superfície de afastamento (30), formada sobre uma porção saliente (31), que através de um afastamento escalonado se estende em uma superfície de afastamento torcida de modo helicoidal secundária, cujo ângulo de cavaco aumenta com o aumento da profundidade de corte. Com a pastilha de corte considerada em vista plana, a face chanfrada é orientada em ângulo reto na direção da borda de corte principal (24, 25). Graças a essa modalidade, é obtido um ângulo de borda funcional constante ao longo de uma linha de borda em forma de onda, que combinada com o afastamento escalonado e o grande ângulo axial positivo (<244>), possibilita uma aperfeiçoada precisão ao usinar uma ressalto de 90° em uma peça de trabalho, o que contribui para um desgaste mais uniforme ao longo da borda de corte principal e um aumento do tempo de vida da pastilha de corte.
