The factors affecting secondary processing energy consumption and quality of CFRP were more complex than those of traditional materials,which made the existing empirical formulas difficult to apply.Taking the cutting force analysis of CFRP secondary machining as the starting point,the optimization decision problems of CFRP processing parameters were studied by considering energy consumption and quality.Firstly,the effects of fiber angle on CFRP processing form were ana-lyzed,and the cutting force models were derived.Secondly,a multi-objective optimization model was established with three cutting elements and fiber direction angle as variables and cutting energy con-sumption and surface roughness as objectives.A multi-mutation driven particle swarm optimization(DM-PSO)and AHP integrated processing parameter optimization decision-making method was pro-posed.Finally,the feasibility and superiority of the above models and methods were verified by the milling experimental design.
