Abstract
Provided is a numerical control device for improving cycle time and machined surface quality. The numerical control device () comprises: a machining program reading unit () that generates, on the basis of a read machining program, a tool center point sequence indicating a path of a center point of a tool of a machining tool; an interpolation control unit () that interpolates the tool center point sequence generated by the machining program reading unit (); a kinematic conversion unit () that performs coordinate-conversion on the tool center point sequence interpolated by the interpolation control unit () to obtain a control point sequence indicating a path of a control point by which the position of the tool is determined; a smoothing application unit () that performs smoothing by performing smoothing processing on the control point sequence, obtained by the kinematic conversion unit (), with predetermined parameters; and a drive control unit () that controls driving of a machining tool A on the basis of the control point sequence smoothed by the smoothing application unit ().
