The invention provides a die-sharing processing control method adopting multiple pressing machines. The control method comprises the following steps: planning and setting a corresponding number of sub-pressing machines with corresponding specifications according to the sizes of workpieces to be processed, and mounting the sub-pressing machines on the same forging die; setting a global forging curve according to forging technological parameters, conducting parallel synchronous control on the sub-pressing machines according to the global forging curve, performing track monitoring on real-time forging positions of the sub-pressing machines, and further utilizing a fussy control strategy to correct the synchronous deviation values of the sub-pressing machines. The die-sharing processing control method adopting the multiple pressing machines solves the problem that the high quality synchronization performance of the multiple pressing machines is poor, realizes high precision processing of forming parts, and prolongs the service lives of the die and the machine tool body.
