Title:  NUMERICAL CONTROL DEVICE 
Abstract: 
Provided are: a simultaneous synchronous tapping command processing means (16) for analyzing simultaneous synchronous tapping commands; a means (21) for selecting the time constant of main tapping axes (S1, S2), the means (21) comparing the acceleration/deceleration time constants of the S1axis and S2axis of a main set and a subset and selecting the longer of the two time constants; a means (22) for accelerated/decelerated processing along a drilling axis (X1), the means (22) calculating the amount of acceleration/deceleration movement along the Xaxes and moving a tool to the commanded position on the basis of the time constant of the main axes selected by the means (21) for selecting the time constant of the main tapping axes (S1, S2) and on the basis of the commanded rotational speed about the main axes; a synchronous tapping interpolation processing means (23) for calculating and synchronizing the main tapping axes with the drilling axis from the pitch and the amount of travel of the drilling axis, which is the output of the means for accelerated/decelerated processing along the drilling axis (X1); and a main tapping axis synchronous processing means (55) for copying, as synchronous data copied to the synchronous side, the amount of rotation of the main tapping axes, which is the output of a means for synchronous processing along axes ranging from the tapping axis (S1) to the drilling axis (X1).
