Abstract:
With the advent of technology, the demand for high performing materials is always
increasing. Automotive industries, Aerospace industries and other high performance industries
are always in search of materials that provide with high strength values. The industry craves for
materials with high strength values and low weight to gain advantage in high performing
applications.
For this purpose, numerous studies have been performed to search for materials that have
good strength to weight ratio and possess material characteristics that can sustain the highperformance conditions.
Titanium and Inconel are an example of such materials. Titanium alloys have found use
in several industrial applications where high performance is expected of a material while not
increasing the weights. Titanium Alloys have gained good popularity in this regard however the
metal has known to be very challenging when it comes to machining. Titanium has very low
conductivity hence the heat produced while machining is not dissipated easily which causes tool
damage.
Machining (Subtractive Manufacturing) is one of the most prominent methods of
manufacturing till this day and is the most widely adopted mode of manufacturing to get
increased production rates. Machining generally involved the chip removal of a workpiece layer
by layer to obtain a required geometry which causes tool wear specially in case of Titanium as
discussed and induces Sub-Surface Damage to the workpiece.
Metal Cutting is an essential component of the manufacturing facility and since all
operations induce some damage it is critical to optimize manufacturing processes to minimize
damage induced.
