Minimization of surface roughness and residual stress in abrasive water jet cutting of titanium alloy Ti6Al4V

Concrete, ceramics, rocks, metal-matrix composites, titanium alloys and other hard-to-cut materials are frequently cut using the non-traditional cold processing method known as abrasive water jet machining (AWJM). A virtual system is proposed in study to minimize roughness of surface residual stress during AWJM alloy Ti6Al4V. The workpiece simulated environments smoothed particle hydrodynamics (SPH) approach finite element method, respectively. Then, Johnson–Cook law model used obtain cutting temperature operations. To calculate operations, then utilized. Taguchi optimization implemented Thus, optimized parameters such pressure, traverse speed, mass flow rate standoff distance calculated Experimental computational examinations carried out order validate effectiveness efficiency minimization waterjet As a result, by parameters, 23.7% 27.1% reduction measured predicted sample machined part obtained. Also, part’s reduced 26.7% 27.9%, for part, So, quality reliability parts can be enhanced developed
