Accuracy Enhancement with Processing Error Prediction and Compensation of a CNC Flame Cutting Machine Used in Spatial Surface Operating Conditions

“…Teaching [6][7][8] is considered the major compensation method in the machining operation process. However, although the teaching process currently is the main way to improve the accuracy of flame-cutting in production workshops, as it is the error compensation in a 'constant' temperature state it not only lacks thermal deformation data of the workpiece and real-time data of non-uniform temperature field, but it also includes detection errors, which means that a great improvement space still exists.…”

Direct visual servoing framework based on optimal control for redundant joint structures

“…These mechanical structures both overcome intrinsic limitations of the mechanical construction and provide more flexibility during the tasks' performance. In the field of manufacturing processes, requirements such as the complexity of geometric shapes, the accuracy needed in the finished piece and the high speed required for the machining processes have focused the use of redundant joint structures 1,2 . However, controlling a redundant system during this type of tasks involves not only the correct end-effector motion, but also the achievement of correct jointstabilization movements.…”

An Autonomous Robot for Casing Cutting in Oil Platform Decommission

“…Jang et al, studied on human robot interaction technology using a circular coordinate system for the remote control of the mobile robot. And they also configured and tested a smart phone environment that can control the robot [11]. Kumar et al, illustrated the development of a continuous monitoring system in assessing the support performance for safer and smooth operation of roof supports in these working under different geo-mining conditions [12].…”
