Industrial robots are characterized by good flexibility and a large working space, offer new approach for the machining of complex parts with small allowances (extra material allowed subsequent machining). Parts this type (such as aircraft skin parts, wind turbine blades, etc.) easily deformed due to their scale low stiffness. Therefore, these cannot be directly machined according designed model. A feasible method is plan robotic path using point clouds after clamping from onsite measurement...
