Abstract

a presente invenção se refere a um método para formar uma superfície (53) sobre uma peça de trabalho de metal (50), compreendendo uma primeira etapa de usinagem de provisão de uma pastilha de torneamento (1) compreendendo uma primeira aresta de corte (11), uma segunda aresta de corte (12) e uma aresta de corte de nariz convexo (10) conectando a primeira aresta de corte (11) e a segunda aresta de corte (12); de seleção de um ângulo de nariz (a) formado entre a primeira aresta de corte (11) e a segunda aresta de corte (12) para ser de menos do que ou igual a 850. em concordância com a presente invenção, o método compreende as etapas adicionais de adaptação da segunda aresta de corte (12) de maneira tal que esta forma um ângulo de afastamento (¿) de mais do que 900 em uma direção de alimentação (99); de posicionamento de todas as partes da pastilha de torneamento (1) à frente da aresta de corte de nariz convexo (10) na direção de alimentação (99); de rotação da peça de trabalho de metal (50) em torno de um eixo geométrico rotacional (a3) em uma primeira direção; e de movimentação da pastilha de torneamento (1) em uma direção paralela para ou em um ângulo de menos do que 450 relativamente para o eixo geométrico rotacional (a3) de maneira tal que a primeira aresta de corte (11) é ativa e à frente da aresta de corte de nariz convexo (10) na direção de alimentação (99) e de maneira tal que a superfície (53) pelo menos parcialmente é formada pela aresta de corte de nariz convexo (10).
