Abstract
The objective of this research was to study the machining of the superalloy VAT 80A using an experimental alumina-based ceramic tool. The factors in this study were the cutting speed, feed, and the depth of cut, and the responses were the cutting power and the surface roughness of the workpiece. A full factorial design was used, and the analysis of variance was employed to determine the optimal parameters. The optimal parameters found in this paper was vc = 400 m/min, f = 0.15 mm/rev and ap = 0.15 m. The tests showed the viability of using the experimental ceramic tool in the turning of the VAT 80A.
