A numerical value control system that controls a machine tool, by calculating a move command from a work program or a work data for a numerical value control unit, and directly inputting the move command to a servo control section ( ) within the numerical value control unit ( ) from the outside of the numerical value control unit ( ). The numerical value control system comprises at the outside of the numerical value control unit: an analyzing unit ( ) which analyzes a work program or a work data; and an interpolating unit ( ) which carries out interpolation for each axis in a position control period of the servo control section based on output information from the analyzing unit ( ) and cut conditions, where by the numerical value control system controls a machine tool by directly inputting a move command of a binary format prepared in advance by the interpolating unit ( ), to the servo control section ( ) within the numerical value control unit ( ).
