Abstract
A numerical controller controls a machine tool to achieve a tapping operation with high accuracy and satisfactory quality without being constrained by a set axial feed distance and a specified axial feed speed. An analyzing unit (4B) calculates a minimum axial feed distance (L.sub.min) necessary for securing a constant machining program set in an input unit (7). A speed pattern adjusting unit (4C) modifies the axial feed speed pattern so that the constant speed time (T) can be secured. An(??) distributing unit (4A) determines drive instructions for a synchronous tapping operation. A drive control unit (5) gives the drive instructions to servomotors included in a driving unit (3).
