mill grinding allowance

  • Allowance (engineering)Wikipedia

    In engineering and machining an allowance is a planned deviation between an exact dimension and a nominal or theoretical dimension or between an intermediate-stage dimension and an intended final dimension. The unifying abstract concept is that a certain amount of difference allows for some known factor of compensation or interference.
