Abstract
- Due to the problems of sharp tool wear, large drilling force and high temperature during the actual processing of 15-5PH stainless steel, in order to improve the processing efficiency and tool life, this work uses the finite element simulation software AdvantEdge FEM studies the cemented carbide drilling process of 15-5PH stainless steel. The multi-factor orthogonal test method is adopted to analyze the results by range analysis method to study the influence of factors such as tool's point angle, clearance angle and helix angle on axial force and temperature. A brief analysis has presented a picture of change process of the axial force and temperature with time. The results show that the point angle has the greatest influence on the axial force, the clearance angle is the second, and the helix angle has the minimum impact. The helix angle has the greatest influence on the temperature, the point angle is the second, and the clearance angle has the minimum impact on the temperature. Finally, author optimizes the geometric parameters of the drill bit for 15-5PH stainless steel and gets the optimized parameter combination. The optimal combination of parameters are expressed as point angle p = 118°, clearance angle γ = 14°, and helix angle β = 30°.
