ABSTRACT:
The invention is directed to an improved motion control system for controlling multiple motion actuators associated with different axes for moving a member along a defined path. The system is intended to move a member along the defined path as a result of the coordinated motion of two or more essentially independent motion actuators. In accordance with the invention, instead of responding to a servo lag error between a commanded and actual position, the velocity along each axis for each path segment is established by a feedforward data file generated by "looking ahead" at input describing the full path and processing this data, together with machine specific data specifying the operational characteristics (or capabilities) of the machine (e.g. milling machine) to be operated.
