In wiresaw, the abrasives from the slurry are free to move within a slurry film of elasto-hydrodynamic origin, between the moving wire and the ingot. This is a typical free abrasive machining (FAM) process. It has been proposed that in a typical FAM environment, the cutting action is caused by rolling and indenting of pointed abrasives. So to model the wiresaw slicing process it was felt necessary to map at the outset the stresses beneath an indenting abrasive. For this purpose a finite element analysis was carried out using the commercial package of ABAQUS. The present animation shows the effective stresses generated by a rigid conical abrasive indenting into a perfectly elastic medium. This animation can be viewed from a Java enabled brouser. The animation should take some time to load.
