Nesting the unfolded shape of the placed component; and generating a machining path for punching out the unfolded shape of the sheet metal component by a processing machine based on the three-dimensional model of the nested sheet metal component. And a method for manufacturing a sheet metal part. 6. The method for manufacturing a sheet metal part according to claim 5, wherein a nesting rotation direction of the developed shape of the part is made to coincide with a hairline direction of the processing material. 7. A sheet metal part manufacturing apparatus for manufacturing a sheet metal part by arranging a plurality of developed forms of a sheet metal part on a processing material and extracting the expanded form of the sheet metal part from the processing material, A means for creating a three-dimensional model; a means for specifying a development reference line of a development shape of the sheet metal part; a means for setting an angle between a hairline direction of the processing material and the development reference line; Means for setting information as to whether or not to rotate the developed shape of the sheet metal part disposed in the nesting process; means for developing a three-dimensional model of the sheet metal part; and the developed sheet metal part. For the three-dimensional model, if the processing material has the hairline division, based on the angle between the hairline direction of the processing material and the development reference line of the development shape of the part Means for nesting the unfolded shape of the part arranged on the processing material; processing for punching out the unfolded shape of the sheet metal part by a processing machine based on the three-dimensional model of the nested sheet metal part And a means for generating a path. 8. The sheet metal part manufacturing apparatus according to claim 7, wherein a nesting rotation direction of the developed shape of the part is made to coincide with a hairline direction of the processing material. 9. When setting a nesting rotation direction of a developed shape of a part when arranging a plurality of developed shapes of the part on a processing material, first, a development reference line of the developed shape of the part is designated. Setting the angle between the hairline direction of the processing material and the development reference line of the development shape of the part, and then determining whether to rotate the development shape of the part arranged on the processing material during the nesting process Information is set, and if the processing material has the hairline section, it is arranged on the processing material based on the angle between the hairline direction of the processing material and the development reference line of the developed shape of the part. A storage medium storing a program for performing a nesting process on a developed shape of the component.
