Effect of wheel wear in grinding of structural ceramics Academic Article uri icon

abstract

  • The effect of wheel wear on process responses and component quality in creep-feed grinding of alumina is investigated. The diamond grits in the wheel working surface developed worn-flats and sometimes microfractured. The grinding forces and power increased, but the roughness decreased with increased wear of diamond grits. The bars ground with as-dressed wheels exhibited a larger reduction in flexural strength than those ground with wheels with worn-flat grits. Indentation fracture models are employed to explain the different fracture behaviors of ground bars. Implications for creep-feed grinding practice are suggested.
