Abstract: The present invention provides a parts processing stage control method and a parts processing stage controlling program by which the progress in parts processing can be instantly recognized. In accordance with the method and program of the present invention, a control computer records the starts times and the end times of pre-processing, main-processing, and post-processing, in a performance time memory unit in a parts processing operation. Based on a performance report as to each storage box, the control computer also records the completion time and the produced quantity for each storage box through the reading of the bar code on the packaging card attached to each storage box. The control computer further records a defect occurrence time when a defect occurrence report is made, in a defect occurrence information memory unit, as well as the contents of the defect.
