The invention relates to a dispatching system for feeding machine tools. According to the dispatching system for feeding the machine tools, materials can be fed to the lack-of-material machine tools more timely, the waiting time of the lack-of-material machine tools is shortened, the utilization rate of the machine tools and corresponding manufacturing resources is improved, and the manufacturing cost is reduced. The dispatching system for feeding the machine tools comprises the workpieces, a warehouse, an overhead travelling crane, temporary storage warehouses and the machine tools, wherein the temporary storage warehouses have automatic feeding functions, the temporary storage warehouses can automatically feed the machine tools corresponding to the temporary storage warehouses, and the automatic feeding functions of the temporary storage warehouses mean that the to-be-machined workpieces which are stored in the temporary storage warehouses are conveyed to the corresponding machine tools for machining through the temporary storage warehouses when the corresponding machine tools are lack of the materials, and then the to-be-machined workpieces are conveyed from the warehouse to the temporary storage warehouses through the overhead travelling crane for temporarily storing. The dispatching system is used for dispatching the feeding of the machine tools.
