Spindle Rotational Speed Effect on Milling Process at Low Cutting Speed

Procedia CIRP, 2014
AbstractThe spindle rotational speed fluctuates during milling due to intermittent cutting forces applied to the spindle, but the speed effect when machining with a relatively large cutter at low cutting speeds is still not clear. The focus of this paper is to investigate the effect of spindle servomotor dynamic characteristics on milling processes at ...
