Drilling Simulation of AA7075 T351 Graded Aluminium Alloy Using Deform-3D

The article develops a three-dimensional drilling model using DEFORM-3D software based on the Usui Tool Wear model, the Johnson and Cook model and the Lagrangian approach. Thermal, structural and chip morphology analyses were performed in this section. The effect of output responses is examined through the lens of their simulation results. The workpiece is made of AA7570 T351 Aluminium alloy with machining type and the drill bit is made of tungsten carbide (WC) with a diameter of 10 mm. Due to its high strength and resistance to corrosion, this alloy is widely used in the aerospace and biomedical equipment manufacturing industries. Thermal analysis reveals that the tool's maximum temperature is 254.8 °C, while the highest temperature is 273.1 °C in the case of AA7075 T351 graded alloy workpiece.
