Abstract:

Dry machining in today&rsquos modern manufacturing system is becoming very popular but dry
machining has been challenging for high strength materials without the use of cutting fluids.
Titanium, also well-known as wonder metal, has a wide range of applications in various industries
for desirable properties (lower density, higher tensile power and resistance towards corrosion in
aqua region, liquid chlorine and seawater). Because of its poor thermal conductivity and higher
chemical reactivity, it has been termed as &lsquodifficult to machine&rsquo material. This situation
necessitates proper selection of the machining parameter as well as cutting tool material before
machining the workpiece. The present work has been carried out exploring the effect of surface
texturing cutting tools on dry turning Titanium grade 23 through experimental and numerical
investigations. Cutting performance was analysed and compared using both uncoated and coated
tools. Machinability criteria had been studied on the basis of cutting forces(Fx, Fy, Fz), cutting
temperature, tool wear, chip morphology. A 3D numerical investigation has been carried out
comparing the performance of textured tools in conventional machining as well as vibration
assistance. The cryo-treated and tempered textured inserts had been taken for dry turning of
Titanium Grade 23 in experimental investigations. The effect of cryo-treatment and tempering
on carbide tools with and without textures have been studied.
