Modeling and simulation techniques have frequently been utilized to analyze manufacturing processes. The simulation of Numerically Controlled (NC) machine tools is preferred to real machine testing of the programs due to the potential savings of time and money. By validating these NC programs in a virtual environment, damage to valuable machines and cutting tools can be prevented, and production would not be interrupted in the factory. However, little work has been done in applying modeling and simulation techniques to the analysis of sustainable machining. This paper introduces research work to integrate traditional virtual NC machining model with sustainability models for environmental impact analysis of machining operations. Aspects of sustainable machining modeled and evaluated include energy consumption, coolant and lubrication usage, and waste management. The technique of Life Cycle Assessment (LCA) was applied for this task. A prototype of machining simulation model was created. The sustainability impact analysis modules were developed and integrated.
