The jump conditions generated are input to the feed control unit. The apparatus includes an input unit for inputting machining conditions relating to the jump conditions in precedence to machining, and a numerical control unit for determining various parameters in dependence on the machining conditions. The parameters are input to the jump condition estimating unit for estimating the jump conditions through feed-forward control using the parameters.
