Abstract

PROCESSO DE USINAGEM DE UMA FACE DE UMA LENTE OFTÁLMICA. O processo de usinagem de uma face (3) de uma lente oftálmica (1) compreende uma etapa principal de usinagem no decorrer da qual a posição de uma ferramenta de usinagem (8) é sincronizada com a posição angular da lente oftálmica (1) acionada em rotação em tomo de um eixo de rotação (4) transversal à dita face (3) de modo a usinar na dita face uma superfície assimétrica em relação ao eixo de rotação (4) da lente oftálmica (1), e compreende por outro lado uma etapa complementar de usinagem de um entalhe (22) em tomo do eixo de rotação (4) da lente oftálmica (1).
