چکیده | ||
This paper presents the findings of experimental investigations into the effects of cutting speed, feed rate, depth of cut and approach angle on the machinability of titanium (Grade-5) alloy. Also the comparison for the two different cutting materials inserts polycrystalline diamond (PCD) and cubic boron nitride (CBN) with similar tool geometry for similar machining parameters is also carried out. Design of experiment technique i.e. response surface methodology (RSM) has been used to accomplish the objectives of the experimental study. The experimental plan for four factors at three level using face centre, centred composite design (CCD) was employed. The results indicated that the approach angle as a dominant factor on the surface roughness and the tangential force evaluation as machinability criteria .The PCD insert showed that in comparison to CBN cutting inserts have better surface finish and smaller cutting force for the level of parameters considered for investigations in machinability study of Titanium (Grade-5) alloy. | ||
