MARGIN CALCULATING APPARATUS AND METHOD FOR CALCULATING MARGIN

摘要

PURPOSE: A margin calculating apparatus and a margin calculating method are provided to increase accuracy of margin decision. CONSTITUTION: An information input part brings welding line information of a main plate and a manufacturing process of a member from a database (S110). A main plate margin calculation part calculates the margin of the main plate to offset the amount of contraction of the main plate when the welding is performed along the welding line of the main plate (S120). A member margin calculation calculates the margin of the member according to the manufacturing process sequence of the member welded to the main plate (S130). [Reference numerals] (AA) Start; (BB) End; (S110) Input information about the welded line; (S120) Calculate the margin of a main board; (S130) Calculate the margin of a member; (S140) Calculate the margin of the first and second main boards
