摘要
Recently, a novel manufacturing technology has spread out with a five-axis machining center. It is especially important to keep the surface roughness on an entire machined surface constant. Thus, we proposed a novel method for maintaining a constant feed speed vector at the cutting point between the end-mill tool and the workpiece surface by controlling two linear axes and a rotary axis with a five-axis machining center. In the present report, we focused on machining the combined inner and outer radius curvature and investigating the influence of synchronous control error between the linear axes and rotary axis on the machining accuracy and surface roughness. As a result, we determined that it is possible to suppress sudden change in the synchronous motion error by accurately aligning the motion direction of the linear and rotary axes and the feed speed vector at milling point at the contact point of the inner and outer circles.
