Experimental Investigations into Hard-Rock Removal Processes Using a Segmental Diamond Wheel

A model one-segmented diamond wheel was developed and used for cutting blocks of hard-rock in an experimental sawing machine. The rock material used was of the Impala and Colombo types of granite.

With the aim in mind of optimising the tool configuration, tests were performed under various cutting conditions:
  1. (i)

    The forces acting in the tool were measured and their dependence on the cutting parameters is discussed.

  2. (ii)

    The wear mode of the segmental wheel was also investigated; the grain wear characteristics were defined by examining the worn surface of the wheel.
