“…Drilling of composites has been very challenging machining operation and from past two decades the research has been continuously thriving in order to obtain a uniform hole quality in composites. Various non-traditional methods of machining are carried out on composites such as abrasive water jet machining (Hejjaji et al, 2017;Tripathi et al, 2020), laser machining (Akman et al, 2019;Gautam & Singh, 2018;Jaeschke et al, 2018;Park et al, 2019), and electrical discharge machining (Islam et al, 2017;Lau et al, 1990;Mazarbhuiya et al, 2020). Drilling and other machining techniques determine the significant role of composites in applications such as automobile, aerospace, and other industries (Cavalier et al, 2006;Godara & Nagar, 2020;Pervaiz et al, 2016;Prolongo et al, 2009;Rezaei et al, 2008).…”
