    15/11/2019· The material removal mechanism affects the surface and subsurface quality of the sliced wafers, thus affecting the fracture strength of the slices [18,19]. Therefore, it is necessary to further understand the influencing factors of material removal and surface generation during fixed-abrasive diamond wire saw cutting of silicon crystal.

    Material Removal an overview ScienceDirect Topics

    Material removal by microcutting in this zone can be modeled after Finnie's suggestions (Engel, 1978, chap. 4). By repeating the cycle of generation, removal, and generation of reactive products, dry-type mechanochemical polishing produces a more efficient polishing without inducing damaged layers as in diamond particle polishing.
