Patent ID: 8117952

Claim:
A closed-loop cutting system comprising: a cutting device for cutting a piece of material at a given dimension; a positioning device for positioning said cutting device to out said piece of material at said given dimension; a positioning device controller for controlling said cutting device by sending to the positioning device a target position corresponding to a desired position of the cutting device; at least one dimension sensor for measuring a true dimension of the piece of material; and a position correction module for: receiving the true dimension of the piece of material and an actual position of the cutting device; determining a difference between the true dimension and a target dimension of the piece of material for the actual position of the cutting device; and modifying a signal corresponding to the actual position of the cutting device to correspond to a new position to compensate for the difference and sending the new position signal to the positioning device controller, whereby the positioning device controller is not aware of the new position and treats the new position as it would the actual position; wherein said at least one dimension sensor measures said piece of material after cutting and returns said actual dimension in real time, and said position correction module modifies the signal corresponding to the actual position in real time.
