Specific cutting energy and surface roughness analysis of dry, wet and cryogenic turning of Ti-6Al-4V

Manufacturing systems are designed to generate productivity which is economical and sustainable. Different manufacturing systems are interpreted in various terms which highlight their manufacturing output. Machining represents a major portion of all manufacturing processes. In the present research a turning manufacturing system is designed, experimented and analyzed to highlight the importance of employment of appropriate input parameters. Use of coolant is taken as an input variable in cutting aerospace alloys (Ti-6Al-4V) to analyze the system in terms of output responses including surface roughness and specific cutting energy. Results showed that surface integrity and specific cutting energy can be significantly improved by using an appropriate cooling system. Cutting speed (contribution ratio 57.33%) and feed rate (contribution ratio 92.37%) proved to be the significant input parameters for specific cutting energy and surface roughness respectively. Confirmatory tests optimized the selected responses maximizing process output.
