| description | Recently, a novel manufacturing technology has spread out with a five-axis machining center, which is controlled by three linear axes and two rotary axes, because the synchronous control technologies make it feasible agilely to create a three-dimensional and complicated surface such as propellers and hypoid gears using it. By making use of the characteristics, a method to maintain a machined surface quality of a curved surface shape by synchronous motion between two linear axes and a rotary axis with the five-axis machining center was suggested because it is difficult for a three-axis machining center to accomplish that. Moreover, it was demonstrated that a proposed method made it feasible to prevent a machined error due to the quadrant glitch caused by friction of the ball screw and linear guide of feed drive system. However, we have not discussed the influence of servo characteristic difference between linear axis and rotary axis on the machined shape error by this method. In the present report, 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 to reduce shape error of machined workpiece considering differences of three axes's servo characteristics with an advanced control. As the results, it could be seen that shape error greatly decreased based on the proposed method. |
