    摘要: A numerical control device determines whether or not a spindle is in a cutting state where it machines a workpiece. If the spindle is in a cutting state, the numerical control device calculates a second rotational speed, which is obtained by multiplying a rotational speed of the spindle by a weight corresponding to a force on the spindle calculated based on a torque of a feed shaft, and integrates the calculated value into an index value. If the spindle is not in the cutting state, the numerical control device integrates the rotational speed of the spindle into the index value. The lifetime of a bearing is estimated based on the index value.
