Sustainable manufacturing strategies will need to address the resource efficiency and surface
quality challenges in cutting processes. This paper aims to provide a systematic methodology for
modelling the input and outputs of a turning process to find the best balance between production
rate and input cost, while improving or adhering to the quality standards. Ti6Al4V were cut under
flood cooling using carbide cutting tools and a Taguchi design of experiments was used with
ANOVA. Surface integrity and energy use were measured and analysed for selected cutting
parameters. The experimental results highlighted the importance of selecting optimum cutting
parameters and machining strategy. More energy was consumed at lower cutting parameters,
whilst higher feed rates resulted in less energy consumption, but lower surface finish quality.
These results will also assist to define the boundary conditions for various input parameters.
