Abstract:
A method for sectioning a generally cylindrical and stationary crystalline workpiece generally perpendicular to a longitudinal axis of said workpiece, comprising the steps of:providing a generally elongated wire having a plurality of cutting elements affixed along a length thereof;positioning said length of said elongated wire at a first position generally tangentially against an outer diameter of said workpiece, with said elongated wire extending generally perpendicular to said longitudinal axis;longitudinally moving said elongated wire generally perpendicular to said longitudinal axis;concomitant with longitudinally moving said elongated wire, reciprocally rotating said length of said elongated wire through an arc about said longitudinal axis, while maintaining said elongated wire generally perpendicular to said longitudinal axis; andconcomitant with longitudinally moving said elongated wire and reciprocally rotating said length of said elongated wire through an arc about said longitudinal axis, advancing said wire from said first position generally tangent to said outer diameter of said workpiece to a second position completely through said workpiece, to thereby form a first cut through said workpiece generally perpendicular to said longitudinal axis.
