| Abstract: |
| Compared with conventional manufacturing methods, the additive manufacturing technique enhances mechanical properties. The present investigation of additive manufacturing technique is focused on delamination studies of Onyx-Glass Fiber Hybrid Polymer Composite (OGFHPC) along with surface roughness properties during machining (drilling) of composites through abrasive water jet machining (AWJM). However, delamination is a major issue during machining of OGFHPC. In order to overcome these drawbacks, the fabrication of OGFHPC was carried out using fused deposition modeling (FDM) technology which is an additive manufacturing method with Mark forged Mark Two 3D-composite printer. The machinability studies were conducted for drilling operation through AWJM process with different abrasive mass flow rates, drilling diameters and traverse speeds. These drilling machinability process parameters were optimized through the design of experiments - Taguchi analysis followed by the analysis of variance (ANOVA) and validated through the Harmony Search Algorithm (HSA), Whale Optimization Algorithm (WOA) and Grey Wolf Optimization Algorithm (GWO). It was observed that minimum delamination and surface roughness of OGFHPC were optimized for AWJM at abrasive mass flow rates (450 g/min), drilling diameters (12 mm) and traverse speed rate (30 mm/min). |
