Abstract

In the machining of titanium alloys productivity is adversely affected by rapid tool wear as a consequence of high cutting zone temperature. Recently, dry cutting is becoming increasingly more popular as a means of reducing overhead costs while protecting the environment. From environmental perspective, dry cutting can be characterized as green machining. Reducing or eliminating when possible the use of cutting fluids in green machining means less waste dumped in landfills, less mist in the factory atmosphere, no residue on the chip which will be reflected in reducing disposal and cleaning cost, cleaner workshop floors, and fewer dermatological problem for operators. Dry cutting is ecologically desirable and it will be considered as a necessity for manufacturing enterprises in the near future; therefore, the studies on the machinability of titanium and its alloys under green machining are urgently essential. For that purpose, the performance of PVD-coated carbide tool in green turning of aviation material Ti-64 (36Rc) is undertaken in this study.
In addition response surface model for surface roughness has also been developed. The model predictions have found to agree with the experimental results.

Keywords: Machining, machinability, surface roughness, and response surface model
