Experimental Research on Cutting Forces of 5-Axis Milling of Al-Alloy Blade

摘要

The cutting force in manufacture process was observed with Kistler dynamometer．A special clamp was designed to simulate the real condition ofblade cutting．Series ofexperiments were done．Cutting force reflected structure of the blade and movement of machine．Cutting folrce was changed with feed speed varied and the rotation ofaxis B&C．Resultant cutting force was uniform in back and basin ofblade and increased with cutting speed went up．Resultant foroe was waved in edge of blade．Back and basin forces were lager than edge force in X direction．Force X invoked vibration．
