1. A method for generating control data for manufacturing a product having a designated shape using an additive manufacturing technology, the control data including a path of a nozzle for supplying a material,
the method for generating the control data comprising:
generating shape data of the designated shape to form a virtual stock corresponding to the product;
determining a cutting path for a virtual cutting of the virtual stock having the designated shape by a tool until the virtual stock is finally formed into only chips;
calculating an amount of the chips removed from the virtual stock by the virtual cutting along the cutting path by determining an amount of an overlapped range between the tool and the virtual stock;
determining the path of the nozzle for implementing the additive manufacturing technology along the path of the nozzle based on the cutting path by temporally reversely reproducing the cutting path; and
determining at least one of a motion speed of the nozzle, an amount of supply of the material, and an output of laser emitted to the material based on the amount of the chips removed from the virtual stock.
