Patent ID: 8061345

Claim:
A method for cutting a workpiece in a wire saw, wherein the workpiece is attached to a mounting beam in such manner that the workpiece and the mounting beam form a continuous body, the method comprising: moving the workpiece through a wire along a linear and constant feed direction to perform a cutting of the workpiece, wherein the wire penetrates a surface of the body at two opposing piercing points during cutting, wherein a section of the wire, relative to which the workpiece is moved to perform cutting, has a longitudinal axis that is oriented at a constant angle relative to the feed direction of the wire saw, wherein the constant angle is substantially 90°, moving the wire along its longitudinal axis such that one of the two piercing points is defined as an entry side piercing point and the other as an exit side piercing point, and when one of the two piercing points lies on a surface of the workpiece and at the same time the other of the two piercing points lies on a surface of the mounting beam, the piercing point lying on the workpiece is the entry side piercing point throughout an entire cutting process through the workpiece; and wherein the workpiece comprises at least one cylindrically shaped portion, the mounting beam having a longitudinal axis (L) and a cross sectional area (A) in a plane perpendicular to the longitudinal axis (L) that is asymmetric with respect to a mirror plane that includes a feed direction of the wire saw, and the mounting beam further comprising a bearing surface for the work piece which has a configuration that is adapted to the cylindrical shape of the work piece.
