surface roughness is a significant parameter which determines the efficiency of optical components. surface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. it is meaningful to rapid evaluate the surface roughness through the measurement of different grinding parameters. in this study, a cup diamond wheel (d64) is used in grinding pr...

a high strength nickel chromium alloy (50cr-50ni-nb alloy), commonly referred to as in-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. the purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of inconel 657. the considered parameters...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...

In this paper, the profile of surfaces machined using end mills with flat and ball end tools in modeled. The real kinematics of the tool motion, the static deflection and the run out of the tool are included in the model. The cutting forces are calculated using a semi-empirical method based on orthogonal to oblique conversion of cutting coefficients. The thickness of the uncut chip is used as t...

This paper describes a comparison of tool life between ceramics and cubic boron nitride (CBN) cutting tools when machining hardened steels using the Taguchi method. An orthogonal design, signal-to-noise ratio (S/N) and analysis of variance (ANOVA) were employed to determine the effective cutting parameters on the tool life. The results indicated that the V was found to be a dominant factor on t...

Asso. Prof.,Dept. of Mech. Engg. G.I.E.T, Rajahmundry, A.P, India DGM (Retd.), B.H.E.L, R&D, Balanagar, Hyderabad, A.P, India Abstract Surface roughness, an indicator of surface quality is one of the most specified customer requirements in a machining process. For efficient use of machine tools, optimum cutting parameters (speed, feed and depth of cut) are required. So it is necessary to find a...
