Composite machining is one of the hot researches currently, and optimal cutting parameters are particularly important to get ideal surface and reduce processing cost of workpiece. By comparison, the present paper selects the surface root mean square deviation Sq as the three-dimensional evaluation parameter of surface roughness to reflect the special appearance after cutting accurately. The single-factor experiment and orthogonal experiment were conducted to study the machining defects emerged and effect of parameters on surface roughness when side milling CFRP (Carbon Fiber Reinforced Plastics) with diamond coated carbide tool. The mapping relationship between cutting parameters and surface roughness was established based on the experiment results. Then, the cutting parameters were optimized by using genetic algorithm with two conflicting objectives: material removal rate and surface roughness. The experiment results show that the proposed method is feasible and effective, and can provide references for the actual processing of CFRP.

Coated Carbide

Engineering field nurtures a variety of superalloys and its wide applications due to the inherent properties of such material. The prime concern of working engineers is to explore reliability, quality, economy, and machinability analysis of these superalloys. In this work, sustainable machining of Monel 400superalloy using PVD multilayer coated carbide tool under dry turning was studied. Surface roughness (Ra, Rz, and Rq), power (P) and cutting force (Fc) were addressed as responses. The subsequent effect of cutting speed, feed and depth of cut on the responses was explored through response surface methodology (RSM), statistical analysis of variance (ANOVA) and multiple regression analysis. Details of tool wear was observed via scanning electron microscope (SEM) to know the cutting behavior at interface. Further, the reliability and economic analysis were performed to substantiate the feasibility of cutting insert. The investigation reveals that surface roughness was affected by feed and cutting speed. The increase in cutting speed uncovers lower cutting forces with improved surface finish during dry turning which further reduces the power requirement. The economic analysis shows unit production time and unit production cost based on a single insert PVD coated carbide tool under optimum value condition. The reliability analysis exposes the meantime to repair (MTTR) (5 min), mean time between failure (MTBF) (28 min), availability (84.8%), failure rate (0.03), and reliability (80.5%) for the production system.
