ABSTRACT:
Method and device of servo-controlling a rotating workpiece in relation to a member such a tool capable of translational motion along a system of two mutually perpendicular axes as a function of a desired rate of transit of the periphery of said workpiece past said tool, in which a tangent to said periphery is determined and the tool is slaved to the displacement of said tangent parallel to itself, while the angular position of said workpiece is determined and the speed of the tool is varied along its system of axes as a function of said displacement of the tangent. Application to the automatic welding of odd pieces.
