Closed-loop cutting system

摘要

A closed-loop cutting system comprises a cutting device for cutting a piece of material at a given dimension; a positioning device for positioning the cutting means to cut the piece of material at the given dimension; a position controller for controlling the positioning device; a feedback means comprising a dimension sensor for measuring the actual dimension of the cut piece of material, the feedback means for measuring a difference between the actual dimension and the given dimension and sending signal back to either one of the positioning device and the position controller to effect an adjustment of the position of the cutting device by reducing the difference.
