Abstract
A machine tool control system is provided that is capable of detecting a one-sheet takeout failure. The system includes a workpiece takeout schedule which indicates the plate thickness and number of sheets to be taken out from a stack of workpieces for each product. A one-sheet takeout sensor is also provided to detect when a one-sheet takeout device fails to takeout or suck one-sheet from the pallet of workpieces. In addition, the system includes a restoration setting key which permits an operator to select one of a plurality of modes to continue control operation of a machine tool with a controller when a one-sheet takeout failure is detected. When information from the one-sheet takeout sensor indicates a one-sheet takeout failure, based on the set mode of the restoration setting key, the controller changes the measuring range, the accumulating place for the sucked workpiece, or skips the workpiece takeout schedule based on a detected plate thickness.
