| description | In a method for manufacturing a metal pipe from a metal plate using a forming tool, the position of the tool is optimized simply and correctly by incorporating individuality of the raw material plate into setting of the tool position.As a preparatory stage, a forming process is analyzed by simulation for each plate. Based on result of the analysis, correlation between a deformed shape value of a raw pipe and tool position information is acquired. Then, the forming process for each plate is stored as correlation between the deformed shape value of the raw pipe and the tool position information. During pipe manufacturing, a deformed shape value of the raw pipe is measured actually while a plate is passed. On the basis of the actually measured deformed shape value, a forming process for the raw pipe is expected and assumed (by using the correlation). Tool position information necessary for implementing the expected and assumed forming process is retrieved from the stored correlation. The retrieved tool position information is realized at a stand array. |
