Abstract
The hard and heterogeneous nature of the metamorphic rocks, offer a significant challenge for the machining
of the same. However, these types of materials are finding more and more applications in areas ranging from
construction materials to home appliances. Very often these require machining operation to have finished
products. At present single point based cutting tools are used for machining. This has the disadvantage of
high wear rate and high temperature at the tip of the cutting tool leading to the premature failure of the same.
Previous studies have revealed that, in spite of the hard varieties of cutting tool used, the tool life has little
improvement in machining of rocks. Thus single point cutting tools have got little importance in this
scenario. This research project mainly focuses on the turning aspects of metamorphic rocks using multi point
cutting tool such as self-propelled rotary cutting tools.
