Unformatted text preview: ant impact on the diameter of the drilled hole. 4.3 Tip Error t tip The tip error in the x and y directions ( U xip and U y ) are determined by the superposition of the mean kinematic and static errors (Table IV). The error due to forces is considered with the forces at their nominal dimensions. Table IV Tip error due to kinematic and static effects. Parameter Error
t U xip 0.240µm -0.109µm U tip y Table IV indicates that the error in the horizontal direction is much more significant than the error in the vertical direction. These horizontal and vertical errors in the tip due to combined kinematic and static effects exceed the desired dimensions of the hole. Therefore, a hole of such a small size may not be obtainable from the current drill architecture. From the previous two sections, it is observed that the tip’s error due to static effects is 45% of that due to kinematic effects. Therefore, correction of the kinematic error could lead to significant improvements in the tip’s position and t...
