Manufacturing adjustment system that adjusts manufacturing statuses of multiple machines

A manufacturing adjustment system that adjusts a manufacturing status of a manufacturing facility where a part including multiple workpieces is manufactured,

• the manufacturing adjustment system comprising:
• multiple machines that manufacture the workpieces, the machines each having a measuring instrument that measures dimensions and a machining time of the workpiece;
• and
• a machine controller that controls the machines, the machine controller being connected so as to communicate with the machines,
• the machine controller comprising:
• a measurement information acquisition part that acquires, in real time, measurement information including the dimensions and machining times of the workpieces measured by the measuring instruments of the machines;
• a part dimension calculation part that calculates dimensions of the part based on the dimensions of the workpieces produced by the machines, the dimensions being acquired by the measurement information acquisition part;
• a total machining-time calculation part that calculates a total machining time of the machining times of the workpieces based on the machining times of the workpieces produced by the machines, the machining times being acquired by the measurement information acquisition part;
• a decision part that decides whether the part dimensions calculated by the part dimension calculation part fall within a predetermined range of dimensions and the total machining time calculated by the total machining-time calculation part falls within a predetermined time;
• a tolerance setting part that sets a workpiece tolerance for each of the machines based on a decision result of the decision part when the workpieces are produced by the machines;
• and
• an operation command part that transmits, to each of the machines, an operation command including the workpiece tolerance set for each of the machines.
