Abstract

SISTEMA DE ANTI-RECHAçO DE FERRAMENTA MECáNICA COM SENSOR DE VELOCIDADE ROTACIONAL. Sistema de controle provido para uso em uma ferramenta mecânica. O sistema de controle inclui um sensor de velocidade rotacional apresentando uma massa ressonante e um controlador eletricamente conectado ao sensor de velocidade rotacional. O sensor de velocidade rotacional detecta o deslocamento lateral da massa ressonante e gera um sinal indicativo do deslocamento lateral detectado, de tal modo que o deslocamento lateral seja diretamente proporcional a uma velocidade rotacional na qual a ferramenta mecânica gira em torno de um eixo da árvore giratória. Com base no sinal gerado, o controlador inicia uma operação protetora para impedir a rotação indesejável da ferramenta mecânica. O esquema de controle empregado pela ferramenta mecânica pode iniciar diferentes operações protetoras para diferentes condições de ferramenta.
