TOOL FOR ARRANGING LASER CUTOFF MATERIAL IN AIRFOIL

PROBLEM TO BE SOLVED: To provide laser cutoff material suitable for mass production and relatively easily removable without repeating work taking time and without forming a noxious fluid. SOLUTION: A tool 12 for arranging laser cutoff material inside an airfoil 10 comprises a block and a sprue plate...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide laser cutoff material suitable for mass production and relatively easily removable without repeating work taking time and without forming a noxious fluid. SOLUTION: A tool 12 for arranging laser cutoff material inside an airfoil 10 comprises a block and a sprue plate 62 coming in contact with the airfoil 10 in the span direction, and a mask 78 with a pair of mask members 82, 84 coinciding with the outer face of the airfoil 10. The respective mask members 82, 84 have joint faces adjacent to the airfoil 10 in the installed state. These joint faces impede the movement of the airfoil 10 in the chord direction and prevent the cutoff material from flowing out to a positioning face in drilling of the airfoil 10.
