Embodiment Construction
[0011] In order to realize the purpose of improving cutting efficiency and reducing tool wear, the present invention adopts the following methods:
[0012] Step 1: Based on the Archard model in the tool model of the adhesive wear theory, according to the geometric relationship between the tool and the workpiece in the process of cutting the superalloy workpiece, the adhesive wear change dW is Based on this, the establishment of the wear model of the flank face of cutting superalloy tools
[0013] Step 2: According to the tool flank wear model, determine the relationship between the normal pressure on the tool wear surface and the cutting temperature when the tool cuts the superalloy workpiece with the minimum adhesive wear: P=f(θ);
[0014] Step 3: Determine the relationship between the yield strength of the superalloy workpiece and the cutting temperature σ s =f(θ);
[0015] Step Four: In Take the minimum value that is , the cutting temperature θ corresponding to the...
