Simulation modeling of the stress state of a prefabricated milling cutter with replaceable inserts during machining was carried out in the ABAQUS 2020 program using the finite element method. It has been established that the structural strength of a cutting tool depends on the geometry, material and cutting conditions. Based on the simulation, stress concentrators in a milling cutter with replaceable inserts were identified. The safety factor of the structure has also been determined, which meets the standard requirement. It has been established that a prefabricated milling cutter with replaceable plates during machining under extreme conditions ensures its performance with a margin of 20%. Thus, a prefabricated cutter with replaceable inserts is applicable for machining newly created and restored surfaces after hardfacing.
