Study of the Method on Cutting-Force Modeling Based on the Current of High-Speed Electric Spindles
It is important to build the models for calculating the cutting-forces in high-speed machining, but it is difficult as the special test-bed with the cutting-force measurement system is complicated, cost much and cannot be applied directly on general machining tools. Aiming at the problems above, a new method was put forward about cutting-force modeling based on the current of high-speed electric spindles, in which the cutting-force models could be gained indirectly by analyzing the built-in motor current and the data gotten from cutting experiments on those general machining tools which are installed with electric spindles. Then on a vertical milling machine tool which is equipped with a high-speed electric spindle, a model for calculating the milling force was gotten using the method put forward by this paper. The results show that the method is simple and easy to be used in routine machine tools in plant spots and need no any special test-beds and any complicated measurement systems possessed only in the laboratory conditions.
