چکیده انگلیسی
Diamond embedded tools were fabricated through nickel electroplating of mild steel conical shaped shank for machining of green alumina compacts using Computer Numerical Control (CNC) machine. Flat and pointed end conical tools embedded with different grain sizes viz. â¼117 μm (120 mesh) and â¼20 μm (625 mesh) of diamond particles were used for green machining of alumina. The hardness values of 625 and 120 mesh tools were measured to be 13.79±3 GPa and 11.84±6 GPa, respectively. Diamond embedded tools were successfully used for net shape fabrication of symmetrical and unsymmetrical objects such as cylinder, dental crown, 3D pattern via CNC machining with submicron range surface roughness. Analysis of mechanical properties and Weibull modulus of the green and sintered alumina samples after green state machining revealed that net shape forming via green machining of alumina using diamond embedded tool is viable.
