Abstract: Based on the existing energy consumption research, and according to the empirical relation between the material removal power and the no-load power and machining power of the machine tools, an empirical calculation model for cutting or grinding specific energy is established.The feasibility and correctness of the empirical calculation model are verified by the theoretical model of cutting or grinding specific energy based on cutting or grinding force and its experiment.A cutting or grinding specific energy database system for key components of typical machine tools through measurement and calculation values of cutting or grinding specific energy based on empirical calculation model is designed and researched, which includes the basic architecture, basic database, analysis module of cutting or grinding specific energy and makes it systematized and standardized.Users can quickly implement the functions of adding, deleting, modifying and searching the required data at the software operating interface.
