Abstract
Abstract A MULTIPLE SPINDLE MACHINE TOOL WHEREIN A CROSS SLIDE AT ONE OF SEVERAL WORKING STATIONS CARRIES AN ADJUSTABLE TOOL WHICH IS ADJUSTED IN AUTOMATIC RESPONSE TO SIGNALS PRODUCED BY A MONITORING DEVICE PROVIDED AT ANOTHER STATION TO DETERMINE THE TOLERANCES OF SUCCESSIVE WORKPIECES AND TO PRODUCE SIGNALS WHEN THE TOLERANCE OF A WORKPIECE DEVIATES FROM A DESIRED TOLERANCE. SIGNALS ARE STORED AND ARE UTILIZED TO ADJUST THE TOOL WHEN A SPINDLE WHICH CARRIED A DEFECTIVE WORKPIECE DURING THE PRECEDING CYCLE PLACES A FRESH WORKPIECE INTO REGISTRY WITH THE ADJUSTABLE TOOL DURIUNG THE NEXT FOLLOWING CYCLE.
