Sažetak
Actual research and development in machining processes are focused on improvement of machining performances through higher productivity, tool life and surface quality. One approach to enhance machining performance is to apply cutting fluids during the cutting process. However, due to negative impact on machining process sustainability, researchers have been urged to search for some alternatives to minimize use of cutting fluids. Concept of environmentally friendly machining is offered as the solution of this problem. A suitable strategy of environmentally friendly machining needs to minimize or even eliminate usage of cutting fluids, minimize energy consumption and cutting tools. The way to sustainable machining process through environmentally friendly machining must start from the process level. It begins from the steps that must be taken to implement ecological machining methods in order to make these alternative technologies reliable, environmentally friendly and cost efficient. This paper focuses on an experimental investigation into the role of environmentally friendly machining on energy/power consumptions, tool life, and surface roughness, in the machining of steel 42CrMo4. A comparative study of milling experiments, under dry, compressed cold air cooling and wet cutting conditions was conducted using the same machining parameter set-up. The results of the conducted investigation have shown high efficiency of the developed compressed cold air technological system of environmentally friendly machining not only in comparison with dry machining, but also in comparison with traditional technologies using cutting fluids. Finally, capabilities and advantages of environmentally friendly machining using compressed cold air were reviewed and discussed.
