The instability of the cutting process can easily lead to a decrease in the surface quality of metallurgical saw blades and even cause damage to the tool.This paper establishes a two-dimensional orthogonal finite element model for milling processing of saw blades using the Johnson-Cook material fracture criterion,and verifies the model based on the change trends of chip morphology and stress distribution.By utilizing this model,the effects of cut-ting speed,cutting depth,the rake angle of the tool,and other parameters on cutting force and cutting temperature are examined,and reasonable parameters for saw blade milling are obtained through comprehensive simulation,resulting in good cutting effects in actual pro-duction.
