Abstract

A control information generation device generates control information for controlling an additive manufacturing apparatus that manufactures a layer shape using a bead that is a manufactured object formed by adding a molten processing material to a target surface while moving a processing position along a manufacturing path, and manufactures a three-dimensional shape in which the layer shapes are stacked. The device includes: a bead width correction unit that obtains a corrected width on the basis of the manufacturing path and a reference width of a cross section of the bead, the corrected width being a width of the cross section for allowing the beads to be adjacent to each other without overlapping; a path correction unit that obtains a corrected path on the basis of the manufacturing path and the corrected width; and a control information output unit that outputs control information indicating the corrected path and the corrected width.
