Optimization of Robot Posture and Workpiece Setup in Robotic Milling With Stiffness Threshold

Industrial robot provides a promising alternative in freeform surface milling. However, due to its low stiffness, it is difficult to guarantee the machining quality. While existing research considers mainly the influence of robot posture on stiffness, the workpiece setup's influence is equally important. In this article, to ensure the overall workpiece's robot stiffness meets the requirement of st...
