Abstract
An iterative spline function controlled positioning mechanism such as a machine tool. A movable element of the machine tool is driven about a plurality of axes under computer control along a path formed by a plurality of sections. Each of the path sections is represented in parametric form by spline functions. The element is driven through a plurality of intermediate positions approximating positions on the path sections. An iterative algorithm implemented by the computer permits efficient computation of the intermediate positions.
