ABSTRACT:
An electro/mechanical feedback system and method for displaying the positional and sizing information relative to the hole size formed by closed stripping blades of a wire stripping machine. The feedback system includes a pair of rotary optical encoders that are tied to the respective blade tool holders via adjusting screws. The adjusting screws provide infinite adjustment resolution. Turning the adjusting screws opens or closes the blades. The encoders convert the adjusting screw rotational information into blade translatory information, which is displayed. The displayed information represents positional information of each of the blades as well as the actual diameter of the cutting hole formed by the closed blades at a true zero position. The adjusting screw includes a torque head that limits adjusting screw torque to a predetermined amount. The present invention includes a positive stop used as a home position for each blade. Translating the blade tool holders against the positive stops and slipping the torque heads of the adjusting screws assures accurate home positions for calibrating the feedback system.
