Additive manufacturing residual stress reduction system, additive manufacturing residual stress reduction method, and additive manufacturing residual stress reduction program

摘要

PROBLEM TO BE SOLVED: To provide a residual stress reduction technique for lamination molding capable of reducing residual stress generated in a molding.SOLUTION: A residual stress reduction system for lamination molding comprises: a control information input section 2 input with control information used for control of the lamination molding for irradiating a beam to metallic powder to be laminated and forming a molding 20; a residual stress analysis section 3 analyzing residual stress generated in the molding 20 based on the control information before a start of the lamination molding; a control information correction section 7 correcting the control information based on the residual stress analyzed; and a control information output section 8 outputting the control information after correction.SELECTED DRAWING: Figure 1
