tougher than single crystal diamond but not as wear resistant.
2. Depending on the purity of the diamond it will start to
graphitize once its temperature exceeds 750 degrees centrigrade.
3. While Diamond is 10X better than copper as a thermal conductor it
will oxidize at 1000 degrees centrigrade.
4. Once the tool temperature reaches 750 Degrees centrigrade the
diamond will dissolve in the carbon or carbon steels which is why
diamond is seldom used for ferrous machining.

interaction between the machine and the process because diamond is
only a form of carbon which in its raw form is only a gas.
