Predictive Models and Optimization Techniques for Sustainable Machining

 

Sustainable machining processes are generally known as environmentally benign, and economically and societally-beneficial machining operations. Sustainable machining is aimed at achieving energy-efficiency, environmental friendliness (with reduced negative environmental impact), cost-effectiveness, waste/coolant reduction or elimination, operational safety and reliability, along with no adverse personnel health effects to operators and shop floor personnel. This keynote presentation will summarize recent progress in developing predictive models and optimization techniques for sustainable machining processes. The presentation will begin with a discussion on the significance of sustainable machining, and will then justify the need for implementing dry, near-dry (MQL-based) and cryogenic machining methods as major sustainable machining processes. A metrics-based evaluation of sustainable machining processes will then be introduced for quantitative assessment of process sustainability in machining, focusing on major machining performance measures, also known as machinability elements (tool-life, surface integrity, cutting forces/power/torque, chip-forms/chip breakability, part accuracy, etc.).
