Abstract

"SISTEMA DE CALIBRAçãO PARA AVALIAR OS ERROS DE ROTAçãO DE EIXOS-áRVORE DE MáQUINAS E DE EQUIPAMENTOS ATRAVéS DE UM LASER INTERFEROMéTRICO". Esta invenção trata-se de um método para avaliar os erros de rotação de eixos-árvore de máquinas e de equipamentos utilizando um laser interferométrico. Este método é capaz de medir os erros de rotação radial e axial, bem como os deslocamentos térmicos ('thermal drifts') radial e axial de eixos-árvore. As medições são realizadas pela reflexão do feixe do laser diretamente através da superfície de uma esfera padrão (8). Esta esfera é fixa na extremidade de um mandril com ajuste angular (10) que é montado na placa do eixo-árvore. Em princípio, a medição do laser é similar à configuração que utiliza interferómetro linear para aferição de deslocamento linear. Uma lente convergente (4) é empregada para focar o feixe de laser em um pequeno ponto na superfície da esfera. Um programa computacional foi desenvolvido para adquirir os dados bem como plotar os gráficos polares dos erros radial e axial e as curvas dos deslocamentos térmicos radial e axial do eixo-árvore em função do tempo. Uma aplicação deste calibrador de erros de rotação foi realizada num centro de usinagem de comando numérico.
