MOTION TUNING METHOD OF LINEAR AXES AND ROTARY AXIS UNDER A CONSTANT CUTTING SPEED VECTOR AT END-MILLING POINT WITH A FIVE-AXIS CONTROLLED MACHINING CENTER

摘要

Recently It is difficult to maintain the high surface quality ingenerating curved surface shape under five-axis controlled end-milling. In this study, we aimed at maintaining feed speed vector at milling point by controlling two linear axes and a rotary axis with a five-axis machining center, to improve machined surface quality and suggested a method for solving shape error of machined workpiece considering differences of three axes's sarvo characteristics. As the results, it could be seen that shape error greatly decreased based on the proposed method.
