Abstract

Analysis of the ceramic stock removal system is a complex process, basically involving the transfer of energy from the grinding wheel to the ceramic workpiece. This involves the various factors generally accompanying the phenomenon of material failure under ballistic impact. However, the shock front normally encountered in ballistic impact is not generated here, since the impact velocities are subsonic. On one hand, this simplifies the matter by avoiding the complications associated with shock front propagation while on the other hand theoretical schemes to analyze the fracture under subsonic impact are not as fully developed as those for the shock front propagated fracture. Furthermore, the existing theoretical models for either the static or the shock failure cannot be directly applied to the stock removal process for at least the following reasons:
  1. 1.

    Many major phenomena act simultaneously, such as high velocity impact, crack propagation, wear and friction processes.

     
  2. 2.

    Experimental parameters: specific conditions and their variations are often extreme. As an example, interfacial pressures may reach levels of 25 kilobars, within one tenth of a microsecond; temperatures of around 1500° Kelvin are experienced.

     
  3. 3.

    The process is a continuous dynamic process; that is, there is a very definite time period over which the material continues to be subjected to impact parameters, after the initial impact is made.
