Method of aligning a cutting tool

1 . A method for aligning a cutting tool comprising:

displacing a first slide comprising a microscope in a first direction at a first speed;

displacing a second slide comprising an adjustable tool holder and a cutting tool in a second direction at a second speed; wherein the adjustable tool holder is in operative communication with the cutting tool;

observing an actual path of travel of a cross hair center of the microscope with respect to a cutting edge of the cutting tool; and

adjusting the position of the cutting tool so that the cutting edge of the cutting tool and the cross hair center lie in the same plane during the travel of the cross hair center.

2 . The method of claim 1 , wherein the first direction and the second direction are mutually perpendicular.

3 . The method of claim 1 , wherein the first speed and the second speed are selected to permit the cross hair center of the microscope to travel in the plane that encompasses the cutting edge of the cutting tool.

4 . The method of claim 1 , wherein the first speed is the same as the second speed.

5 . The method of claim 2 , wherein the first speed is different from the second speed.

6 . The method of claim 1 , wherein the plane is a vertical plane.

7 . The method of claim 1 , wherein the cutting tool is aligned by manually adjusting the adjustable tool holder.

8 . The method of claim 1 , wherein the cutting tool is aligned by using a micrometer.

9 . The method of claim 1 , wherein the cutting tool is aligned by using a numerically controlled positioning stage.

10 . A drum manufactured by the method of claim 1 .

11 . A replica tool manufactured from the drum of claim 10 .

12 . A brightness enhancing display film manufactured from the replica tool of claim 11 .

13 . The brightness enhancing display film of claim 12 having a misalignment angle of up to about ±2 degrees.

14 . A device that employs the brightness enhancing display film of claim 13 .

15 . The method of claim 1 , wherein the cutting tool is a diamond-cutting tool.

16 . A method for aligning a cutting tool comprising:

locating a cross hair center of a microscope above a first point on a cutting edge of a cutting tool; wherein the cross hair center and the first point lie in a plane;

displacing a first slide comprising the microscope in a first direction at a first speed;

displacing a second slide comprising an adjustable tool holder and the cutting tool in a second direction at a second speed; wherein the adjustable tool holder is in operative communication with the cutting tool;

terminating the displacement of the first slide and the second slide;

observing a second point on the cutting edge of the cutting tool with the cross hair center of the microscope; and

adjusting the tool position to permit the second point and the cross hair center to lie in the plane.

17 . The method of claim 16 , wherein the first direction and the second direction are mutually perpendicular.

18 . The method of claim 16 , wherein the plane is a vertical plane.

19 . The method of claim 16 , wherein the cutting tool is aligned by manually adjusting the adjustable tool holder.

20 . The method of claim 16 , wherein the cutting tool is aligned by using a micrometer.

21 . The method of claim 16 , wherein the cutting tool is aligned by using a numerically controlled positioning stage.

22 . A drum manufactured by the method of claim 16 .

23 . A replica tool manufactured from the drum of claim 22 .

24 . A brightness enhancing display film manufactured from the replica tool of claim 23 .

25 . The brightness enhancing display film of claim 24 having a misalignment angle of up to about ±2 degrees.

26 . A device that employs the brightness enhancing display film of claim 25 .

27 . The method of claim 16 , wherein the cutting tool is a diamond-cutting tool.

28 . A method for aligning a cutting tool comprising:

selecting two or more points on a first cutting edge and two or more points on a second cutting edge of a cutting tool; wherein the selecting is accomplished with a cross hair center of a microscope;

determining mathematical equations to the first cutting edge and the second cutting edge;

mathematically determining a location of a cutting tip of the cutting tool with respect to a drum;

directing travel of the cross hair center according to the mathematical equations for a desired location of the first cutting edge or the second cutting edge; and

adjusting the cutting tool to permit the travel of the cross hair center to trace a path that encompasses either the first cutting edge, the second cutting edge or both the first cutting edge and the second cutting edge.

29 . The method of claim 28 , wherein the first cutting edge and the second cutting edge intersect at the cutting tip, and wherein the cutting tip is selected as a point for determining the location of the first cutting edge and/or the second cutting edge.

30 . The method of claim 28 , wherein the cutting tool is aligned by using a numerically controlled positioning stage.

31 . The method of claim 28 , wherein the cutting tool is aligned by manually adjusting the adjustable tool holder.

32 . The method of claim 28 , wherein the cutting tool is aligned by using a micrometer.

33 . The method of claim 28 , wherein the first cutting edge and/or the second cutting edge is linear.

34 . The method of claim 28 , wherein the first cutting edge and/or the second cutting edge is parabolic.

35 . A drum manufactured by the method of claim 28 .

36 . A replica tool manufactured from the drum of claim 35 .

37 . A brightness enhancing display film manufactured from the replica tool of claim 36 .

38 . The brightness enhancing display film of claim 37 having a misalignment angle of up to about ±2 degrees.

39 . A device that employs the brightness enhancing display film of claim 38 .

40 . The method of claim 28 , wherein the cutting tool is a diamond-cutting tool.
