METHOD FOR DESIGNING RESIN-COATED SAW WIRE

WIPO Patent Application WO/2011/105450

A1

Provided is a method for designing a resin-coated saw wire such that when a workpiece is cut off using a resin-coated saw wire formed by coating the surface of a steel wire with resin, the depth of a machining-altered layer is shallow, and a cut body having a smooth surface can be obtained. (1) A steel wire is coated with resin having predetermined hardness. (2) A workpiece is cut off using the resin-coated saw wire obtained. (3) The depth of the machining-altered layer on the cut crosses section of the workpiece is examined. (4) Acceptance or rejection of the depth of the machining-altered layer is checked. (5) In the event of rejection, a steel wire is coated with further hardened resin, and items (2) to (4) are repeated, and thereby, resin hardness is adjusted so that the depth of the machining-altered layer on the cut cross section of the workpiece will be accepted.
