Cost and Process Information Modeling for Dry Machining

The cost of using coolant in machining industry world-wide is very high. Through a literature survey, it costs multi-billion Dollars for coolant acquisition and disposition in industrialized countries. Furthermore, chemical substances contained in coolant are very harmful to environment and machine shop workers. Dry machining is inevitably the future trend in machining industry. In order to help dry machining methods be smoothly adapted by the industry, this paper provides an information model for cost and process of dry machining. New software tools and knowledge databases can be developed based on this model to help users to choose optimal process parameters, resources, and estimate machining time and cost. This model is in its early stage. Extension to this model is expected as dry machining technology advances.
