Abstract: Provided is a numerical control method in an apparatus having a C-axis control function for numerically controlling a spindle in the direction of rotation. The method includes providing a first G-code word (Gg1) for achieving agreement between axis control characteristic values of a C-axis motor control system and axis control characteristic values of a feed-axis motor control system, as well as a second G-code word (Gg2) for restoring axis control characteristic values changed by the first G-code word to original values, making spindle control characteristic values agree by commanding the first G-code word before controlling the C axis at the same time as the feed axis, and restoring to original values the spindle control characteristic values changed by the first G-code word by commanding the second G-code word after simultaneous control of the C axis and feed axis ends.
