N2 - Free abrasive machining (FAM) using a wiresaw is emerging as a state of the art technology for slicing large diameter semiconductor wafers. Material removal in a FAM environment is known to be by rolling and indenting of abrasives into the cut media. Therefore, indentation by abrasives in the slurry is the single most important mechanism in wiresawing process. This paper deals with the importance of abrasive shape in material removal during FAM. To achieve this objective, indentation by conical rigid abrasives of different included angles has been investigated using finite element method (FEM). Typical indentation fracture involving median, radial and transverse cracking has been explained to the maximum level of sophistication attainable using static stress analysis. Some industrially relevant results pertaining to FAM in general and wiresawing in particular have been proposed.
