Abstract:

Increasing demand for improving the strength of Aluminium Alloy (AMCs), which are widely used in the aerospace, automobile, and defence industries, has been seen in recent years. Aluminum 7075 (Al-7075) is a widely used aluminium alloy because of its high wear opposition and process-ability. By dispersing a suitable combination of Boron Nitride in the aluminium alloy, new techniques are being developed to im-prove the hardenability, strength and hardness of the composite. However, these hard-reinforced composites pose a number of difficulties during the machining process using WEDM process. The performance measures and surface topography acquired and input process parameters are also need to be observed and explained with aid of Taguchi-DEAR methodology. The material removal rate and kerf width have been checked and evaluated using Taguchi-DEAR methodology. The proposed method can efficiently enhance the cutting process with les tool wear and heat affected zone. 32 µs (Ton), 36 µs (Toff), 3.5 A (I), and 4.74 m/min (WF) were discovered to be the optimal arrangement of input factors in the WEDM process, with an error accuracy of 1.6%.
