The present invention relates to navigation of a path by a moving object, and, more particularly, to motion control systems for computer-controllable machine tools.

Method of performing additive lookahead for adaptive cutting feedrate control

Method of curvature controlled data smoothing

A method of controlling movement of a body at spaced apart instances along a trajectory in a multi-dimensional environment by determining a current position of the body at a current instance, determining an ideal point on the trajectory, determining a vector difference between the current position and the ideal point, and adjusting the body's velocity for a subsequent instance based on the vector difference. The method may be used in motion control systems for computer-controllable machine tools.

Method of tolerance-based trajectory planning

A computer-controlled machine equipped with sensors determines position and orientation of a workpiece, with respect to a model of the workpiece, which is stored in a data processing system interfaced to the machine, by measuring coordinates of points on the surfaces of the workpiece and determining a transformation in which a sum of squared distances from the points to the corresponding surfaces of the model is minimized. The determined transformation is improved so as to satisfy the specified tolerances.
