Abstract：
In order to ensure accurate key parameter configuration of a shield machine and seize the opportunity for disc cutter replacement, a visualized breaking force forecast model for disc cutters was established through a mathematical deduction by CSM model and a wear rate forecast model of the disc cutter was set up by analyzing the disc cutter wear mechanism based on the abrasive wear mechanism. Since there are some approximate calculations in the process of model derivation and great changes to parameters in the operation of a disc cutter, an error analysis of the derived models was carried out. Finally, the correctness of the two models was determined through field measured data.
