Abstract
In order to level up the 3D complex shape machining for the metal mold and die, the machining simulation which can be considered the contact point or relative angle between the workpiece and machining tool is useful. In this study we has been developed the technique which calculates the interference quantity of the cutting edge and the workpiece for the ball-nosed end milling. In this report the new machining test method at any tool orientation used by 3axis controlled machine tool is presented, and the relationship between machining accuracy and the tool orientation is discussed.
