HIGHLIGHTS
- The RSM method is an effective tool for modeling the turning process of the Ti6Al4V titanium alloy.
- The use of a polycrystalline diamond cutting insert for dry turning enables environmentally friendly machining.
- Too high temperature during the cutting process leads to the release of chemical compounds.
- Multi-criteria optimization of the turning process enables to obtain cutting parameters that meet the quality requirements.

ABSTRACT
The paper depicts an application of Response Surface Methodology (RSM)
for predicting selected parameters in turning of Ti-6Al-4V titanium alloy using polycrystalline diamond tool. Response surface plots that are generated by
the model helps in determining the optimum combination of input factors (cutting speed vc and feed rate f) for best possible surface roughness (Sa), cutting
force (Fc)and temperature (T) for dry and cooling turning. The methodology of
multi-criteria optimization was used to establish the interaction between input
parameters and given responses
