A numerical controller which can freely and easily specify, as a control point, various positions on a machine configuration and which can easily set coordinate systems in places on the machine configuration. A numerical controller expresses the machine configuration of a control target in graph form where constituent elements are nodes and holds the machine configuration. The numerical controller includes: a control point coordinate system specification portion that specifies, with the identifier, one or more groups of the control point and the coordinate system; a command value determination portion that uses the specified control point and the coordinate system to determine for which control point and on which coordinate system one or more command values commanded in a program correspond to a coordinate value; and a movement command portion that commands a move of the control point such that the coordinate value of the control point is the command value.
