Analysis of Machining Parameters in WEDM of Al/SiCp20 MMC Using Taguchi‐Based Grey‐Fuzzy Approach
Modelling and Simulation in Engineering, Volume 2019, Issue 1, 2019., 2019 Aluminium silicate metal matrix composite (AlSiC MMC) is satisfying the requirement of material with good mechanical, thermal properties, and good wear resistance. But the difficulties during the machining are the main hurdles to its replacement for other materials. Wire electric discharge machining (WEDM) is a very effective process used for this type
