Abstract
A numerical control device according to the present invention is for a machine tool which causes a tool to move along a movement path decided according to a machining program, and includes: a limit setting storage unit in which limit values of a plurality of parameter related to movement of the tool are set; a limit velocity calculation unit which calculates a plurality of limit velocities which are movement velocities of the tool, which respectively correspond to the limit values of the plurality of parameters at each position of the movement path; a feedrate determination unit which defines a minimum value among an ideal velocity of the tool and the plurality of limit velocities at each position on the movement path as a feedrate of the tool at each position on the movement path; and an adjustment effect calculation unit which calculates variation in movement time required in order to cause the tool to move an entirety of the movement path at the feedrate, in a case of changing the limit value of the parameter.
