Sardinas et al. was the first to utilize such method in CFRP machining optimization, where MOGA algorithm was used to optimize two conflicting objectives in CFRP drilling (material removal rate and delamination damage). As shown in Fig. (b), the obtained Pareto front indicated that the material removal rate increased at the expense of more severe delamination damage. Wang et al. optimized the delamination, burr and material removal rate in helical milling of CFRP. The obtained Pareto front indicated that material removal rate was improved at the expense of more severe delamination and burr damage. Similar methods have been deployed in the optimization of various CFRP machining operations and the details are summarized in Table .
