FUNCTIONALITY OF WING BEND
CONVENTIONAL BENDING
	PUT THE MATERIAL ON THE DIE.	LOAD THE PRESSURE.	IT IS DIFFICULT TO GET THE REQUIRED ANGLE BECAUSE THE MATERIAL IS BENT BEING SUPPORTED AT TWO(2) POITNS OF V DIE. AND THE ANGLE IS UNSTABLE. (AIR BENDING) IN ADDITION, DIE MARK OCCURS AFTER BENDING. IN ORDER TO GET THE REQUIRED ANGLE, YOU NEED BOTTOMING OR COINING BENDING.
WING BEND BENDING
	PUT THE MATERIAL ON THE WING.	DURING THE MATERIAL BEING HELD BY UPPER TOOL, IT IS BENT. SPRINGS MOVE UPWARD IN ACCORDANCE WITH DOWNWARD PRESSURE EXERTED BY UPPER TOOL.	WITH THE FURTHER DOWNWARD PRESSURE EXERTED BY UPPER TOOL, THE MATERIAL IS BENT FIRMLY. THE MORE THE DOWNWARD PRESSURE IS EXERTED BY UPPER TOOL, THE MORE SPRINGS MOVE UPWARD. THE NATURE OF SPRINGS CAUSES RETURN TO THEIR ORIGINAL POSITION. IN OTHER WORDS, THE DOWNWARD PRSSURE EXERTED BY UPPER TOOL FIGHTS WITH THE BACKWARD PRESSURE EXERTED BY SPRINGS. THE MATERIAL BEING SANDWICHED BETWEEN THE UPPER TOOL AND WINGS IS BENT. AS A RESULT, YOU CAN GET THE FINE BENDING ANGLE.
