PROPOSAL OF A DECISION METHOD OF TARGET SHAPE POSITION AND ORIENTATION FOR HIGH EFFICIENT MACHINING OF COMPLICATED WORKPIECE SHAPES

抄録

Metal additive manufacturing (AM) attracts a great deal of attention from manufacturing industries. Thus, a multifunctional machine tool that has not only machining function but also AM function is recently developed to realize high flexibility and productivity. However, it is difficult to expect and control workpiece shapes created by AM. The differences may induce unexpected collisions on a multi-functional machine tool. Additionally, even though machining productivity is affected by the arrangement of target shape, it is difficult to decide the target shape position and orientation according to complicated workpiece shapes. Therefore, this study proposes a decision method of target shape position and orientation using workpiece shape obtained by on-machine measurement to realize high efficient machining of complicated workpiece shapes as created by AM on a multifunctional machine tool.
