Abstract :
In this paper, a design approach for cutting power control of the milling operation is presented. The system is applicable to machine tools featuring speed controlled feed and main motors without additional sensors. The intention is to get a constant load of the milling tool independent of parameter changes of the cutting process. The manipulated variable is the feed speed which has the largest influence on the cutting power. An estimator determines a low order model of the milling process for adaptation of the control system. The inverse process model is used to compute a reference feed which is adjusted by the normal cascaded feedback controller. Experimental results show the quality of the presented control system
