<p>This study examines the impact of various cutting parameters on the cutting mechanism of FeCoCrNiAl<sub>0.6</sub> high-entropy alloy under conventional, single-laser-assisted, and multi-laser-coordinated assisted cutting conditions.

摘要

This study examines the impact of various cutting parameters on the cutting mechanism of FeCoCrNiAl0.6 high-entropy alloy under conventional, single-laser-assisted, and multi-laser-coordinated assisted cutting conditions. Using ABAQUS simulations and cutting experiments, we analyzed cutting force, surface quality, and residual stress. The results show that laser-assisted cutting significantly reduces cutting force. At a cutting depth of 1.25 mm, the force in single-laser-assisted cutting is 85.3% of conventional cutting, and multi-laser-coordinated cutting further reduces the force to 90.5% of single-laser-assisted cutting. Thus, increasing the number of laser sources further reduces cutting force, with multi-laser-coordinated cutting proving most effective. In terms of surface quality, dual-laser-coordinated assisted cutting outperforms both single-laser-assisted cutting and conventional cutting. The residual stress patterns for both single-laser-assisted and dual-laser-coordinated cutting show consistent behavior across depths, with the maximum residual compressive stress increasing initially, then decreasing and stabilizing with depth. Compared to dual-laser-coordinated cutting, conventional cutting and single-laser-assisted cutting generate 82.6% and 89.4% of the maximum residual compressive stress, respectively. Lower cutting speeds during laser processing promote higher residual compressive stress, and the use of more laser sources amplifies this effect. These findings suggest that laser-assisted cutting, particularly with multiple laser sources, offers improved cutting efficiency, better surface quality, and optimized residual stress control.
