Abstract
This study deals with the numerical modeling and analysis of machining characteristics of three aluminum alloys (Al7075-T6, Al6061-T6, and AA2024-T3) during high-speed machining. A parametric sensitivity analysis is performed with six different cutting speeds (180, 360, 720, 1440, 2880, and 6000 m/min) while keeping the feed rate constant (0.15 mm/r). The chip formation mechanism, characteristic of cutting force, exit-direction burr and energy dissipation are analyzed in detail. It is observed that cutting speed plays a pivotal role in the types of exit-direction burr and cutting reaction force. Al7075-T6 with the larger initial yield stress and strain hardening modulus has harder machining characteristic. The results obtained will contribute to further understanding the machinability of aluminum alloys.
