| Abstract: | Based on the mechanism of the serve drive system, the relation model between the milling force and the current signal extracted the serve drive system in an NC system is discussed, and an intelligent adaptive prediction method with strong robustness for the delay of current signal is proposed. Experimental results demonstrate that the indirect modeling method for milling force is able to deal with the bottle neck of the monitoring of milling force in the intelligent adaptive NC machining. |
