Abstract

cabeça de corte. uma cabeça de corte rotativa em torno de um eixo geométrico central inclui uma porção de ponta e uma porção intermediária. a porção de ponta tem um ponto de ponta axialmente mais à frente contido no eixo geométrico central e pelo menos duas superfícies frontais axialmente voltadas para frente, cada superfície frontal tem uma aresta de corte que se estende radialmente. a porção intermediária tem pelo menos dois ressaltos de cabeça alternando circunferencialmente com pelo menos duas passagens de evacuação de arestas, em que cada ressalto de cabeça tem uma aresta dianteira que se estende axialmente para trás a partir da porção de ponta. as arestas de corte estão contidas em uma superfície de anel anular imaginária, e um primeiro plano radial imaginário que contém o eixo geométrico central cruza a superfície de anel anular imaginária para formar dois perfis de corte radiais imaginários. cada perfil de corte radial imaginário tem primeira, segunda e terceira porções de perfil de corte que se estendem consecutivamente radialmente para fora, e a segunda porção de perfil de corte inclui primeira e segunda subporções côncavas espaçadas por uma primeira subporção convexa.
