摘要： A shaped sawing wire adapted to cutting hard materials, comprises a wire having bends with segments in between. The wire has subsurface tensile residual stresses for keeping the shape of the wire while sawing. The sawing wire keeps its shape from the entry of the cut onward till the exit of the wire from the sawing process, which shows a significant improved cutting efficiency.
