METHOD FOR CALCULATING CORRECTED HEATING PROCEDURE IN LINEAR HEATING

Title:

METHOD FOR CALCULATING CORRECTED HEATING PROCEDURE IN LINEAR HEATING

Document Type and Number:

Japanese Patent JP2006218486

Kind Code:

A

Abstract:

To provide a calculating method of a corrected heating procedure at practical speed.

An estimation polynomial for approximating the relationship between a heating rate and an amount of deflection is obtained by selecting representative points from on a metallic sheet, drafting a simulation program having orthogonality for giving variation to the amount of deflection of each representative point, calculating the heating rate by which the above variation by the simulation program is obtained from a data base having the relationship between a preliminarily prepared heating conditions and deformation and the corrected heating rate is calculated by substituting the actual amount of the deflection of each representative point by a measured actual shape for the estimation polynomial.
