The work, which was performed in the period from 12/6/79 to 9/30/81 included: (1) rock cutting experiments with single point polycrystalline sintered diamond compact (PDC) cutters to quantitatively determine cutter wear rates and identify wear modes, (2) PDC rock cutting experiments to measure temperatures developed and examine the effects of tool wear, cutting parameters and coolant flow rates on temperature generation, (3) assisting in performing full scale laboratory drilling experiments with PDC bits, using preheated air to simulate geothermal drilling conditions, and in analyzing and reporting the experimental results, and (4) acting in a consulting role with the purpose of establishing design specifications for geothermal hard matrix PDC bits to be procured by Sandia Laboratories for test purposes.
