A grinding robot for grinding an electrically conducting workpiece. The grinding robot includes a grinding wheel, an actuation device for actuating grinding wheel, and a control system. The grinding wheel including an undulated tool receptacle which defines an axis of rotation about which the grinding wheel can rotate during grinding, and a head which is rotationally symmetrical with respect to the axis of rotation, and which contains abrasive material and has a grinding surface which is in contact with workpiece during grinding. The grinding wheel also includes a measuring and transmission unit and at least one conductor strand pair with two conductor strands which are electrically insulated from one another. The conductor strands are embedded in the rotationally symmetrical head and extend from the grinding surface of the head into the interior of the head and are electrically connected with measuring and transmission unit.

In the present application, a shaped article W is produced, the shaped article including: a plurality of blades provided around a shaft, with an interval disposed therebetween in the circumferential direction; and curved surface-shaped recesses present in between the blades. This method for producing a shaped article includes: a shaping step, in which welding beads where filler material has been melted and solidified at the peripheral surface are layered on a base material having a circular cross-section of a greater radius than the bottom circle that passes through the lowest part of the recess, thus forming a shaped section that will become a blade; and a cutting step in which part of the surface of the shaped section and the peripheral surface of the base material is cut to form a blade, and the recesses between the blades are also formed.

A wind power blade multi-robot cooperative grinding and roller coating operation assembly line system is provided and includes: a working platform; a blade tip transfer and tooling turning system and a blade root transfer and tooling turning system arranged on a middle of the working platform and configured to support and adjust a head and a tail of the wind power blade respectively; wind power blade automatic grinding robots and wind power blade automatic roller coating robots symmetrically arranged on the working platform and located on two sides of the wind power blade. An automatic processing of grinding and roller coating of wind power blades is realized, which can reduce labor intensity. An integration of omnidirectional transfer and weight of the wind power blades is realized, which can detect the weight in real-time. A blade sprain is avoided effectively, and a layout of an assembly line is more flexible.
