Patent ID: 8109004

Claim:
A scribing system comprising: (A) a mounting mechanism that is configured to rotate an elongated object, wherein the elongated object has a middle portion, a first end, and a second end, the elongated object having a long dimension bounded by said first end and said second end, wherein the middle portion of the elongated object is subjected to a bow effect a displacement, at a time when the elongated object is being scribed, relative to the first end and the second end, wherein the displacement is less than ±10% of a length of the long dimension; (B) a stylus for scribing the elongated object at a position x along the long dimension of the elongated object, while the mounting mechanism rotates the elongated object and thereby subjects said elongated object to said displacement; and (C) a force generating mechanism connected to the stylus so that the stylus applies a force within ±20% of a stated force value to the elongated object regardless of the position x along the long dimension of the elongated object that the stylus is positioned, while the mounting mechanism rotates the elongated object and thereby subjects said elongated object to said displacement, thereby scribing the elongated object.
