CA 2747239

The present invention relates to navigation of a path by a moving object, and to motion control systems for computer-controllable machine tools. There is provided a method of computing velocity limitations for a plurality of motion commands provided to a motion controller to cause an object to move along a trajectory. A look- ahead queue includes a plurality of motion commands. A first stop distance for the first motion command is calculated based on the distance between a first target point and a first virtual point beyond the first target point. A second stop distance for the second motion command is calculated based on the distance between a second target point and a second virtual point beyond the second target point. A computing device modifies a velocity limitation for the first motion command by reducing the first stop distance based on the second stop distance. The first motion command is then provided to the motion controller.
