Abstract
A feedback apparatus used in combination with a programmable machine controller for a multi-spindle screw machine wherein each spindle has a corresponding machine tool mounted on a moveable servo slide. The feedback apparatus includes at least one measurement device that produces an electrical output indicative of a dimensional characteristic of each work piece. The measurement device data is inputted to a data analyzer that calculates average values and range for a predetermined subgroup number of work pieces. The analyzer provides this data electronically to a programmable offset device that determines new offset values for the machine tool slides to maintain the subgroup average values and range within predetermined limits. The feedback apparatus provides 'on the fly' offset updates to the machine controller to compensate for average machine process performance as well as individual machine tool and spindle performance.
