<p><P>PROBLEM TO BE SOLVED: To provide a production circumstance display device for instantaneously grasping production circumstances by a machine tool. <P>SOLUTION: Plan data including a program substitution time and a recess are displayed at a display as a graph format. When the production of a work piece by a machine tool is started, result data including the model of a workpiece and the completion time of working are prepared each time a completion signal is output from the machine tool, and the result data are plotted in a graph where the plan data are displayed on the display. Also, the cumulative number of workpieces based on the plan data at a current time is displayed as "a plan", the actual cumulative number of workpieces based on result data is displayed as a "result", and the difference of the cumulative number of those "plan" and "result" is displayed as a "progress" so as to be superimposed on the graph on the display by numerical notations. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
