Abstract

Se describe un procedimiento para ajustar una máquina esmeriladora controlada por ordenador para esmerilar regiones concéntricas de una pieza de trabajo, en la cual se carga un programa que contiene datos relativos a la pieza de trabajo y un programa que contiene instrucciones para la rueda amoladora y se ejecuta el programa de instrucciones para la rueda amoladora de forma que se esmerile al menos una región de dicha pieza de trabajo hasta su forma final. La región se mide y se toma nota de la magnitud y de la posición angular de cualquier excentricidad indeseada introducida por el proceso de esmerilado y las instrucciones del programa o las señales de control derivadas del mismo se ajustan de forma que durante la esmerilación posterior de dicha región, o de una región similar de una pieza de trabajo similar, la rueda amoladora sea controlada de forma que compense dicha excentricidad detectada. Se eliminan las tensiones sobre la región de la pieza antes de la calibración. Después del ajuste, la máquina esmeriladora esmerilará excéntricamente una región de la pieza que deba tener una superficie cilíndrica concéntrica con relación al eje primario de la pieza, en vez de amolar concéntricamente dicha región, el grado de excentricidad será tal que cuando se eliminen las tensiones sobre la pieza cilíndricamente esmerilada después del esmerilado, la región será concéntrica con relación al eje de la pieza. Se describe una máquina amoladora controlada por ordenador así como los programas para el ajuste y el esmerilado.
