A deburring subassembly has a controller to generate an electrical current and move a deburring tool bit from a non-deburring position to a range of deburring positions. The electrical current permits deburring of the workpiece without damaging it. A workpiece securement subassembly secures the workpiece for formation on a computer numerical controlled (CNC) machine tool and also holds the workpiece in place for deburring. The electrical current is provided to a deburring tool bit. The controller thereby controls movement of the deburring tool bit to the range of deburring positions and generates the electrical current to deburr the workpiece.
