Abstract
Recently, hybrid lubricooling is considered as the emerging sustainable cooling technique and is in a rudimentary stage. The application of hybrid CryoMQL (Cryogenic+MQL) method is getting repute in the industrial sectors due to its benefits, such as less resource consumption and improved productivity. In the past, machining efficiency in term of the trade-off of productivity and energy efficiency has not been explored in-depth for hybrid Lubricooling assisted sustainable machining process. Therefore, in this study, turning experiments were performed to analyze the productivity and machining efficiency in sustainable machining of Ti-6Al-4V alloy. All experiments were performed in different cooling techniques, and comparative results were obtained. Cutting time was fixed for each environment during a particular set of experiments and cutting speed was kept relatively higher in hybrid CryoMQL (HCM) method. Results showed that the HCM method performed best as compared to dry and MQL method. Longer tool life, higher productivity, lower energy consumption can be obtained using the proposed method. The study preaches “Think Green, Plan Green, and Go Green” and the proposed technology can be implemented in the metal processing industry to get high productivity and save cost.
