System, method, and program for manufacturing computer-designed part members of furniture using machining equipment

A furniture product is designed as a rectangular parallelepiped space such that dimension of the space can be altered. Shape and size of a plurality of kinds of machining to be provided on a face of a part member face is registered in a machining master. Toolpath of controlling a tool of a machining machine is produced by CAM for each machining in advance. Machining selected from the machining master is registered on a face of a rectangular parallelepiped space of the part member. Upon receiving the data of rectangular parallelepiped space of the part member having altered dimension, the machining machine can apply the selected machining at a position after alteration of the dimension by controlling the tool in accordance with the toolpath.
