摘要

与传统制造工艺相比，线切割加工提供了许多好处。同样，没有明显的机械切割痕迹，硬质材料也可以在电火花线切割中完美加工。自那以来，铝合金因其高强度重量比、精确的形状和尺寸而被用于航空航天、造船、水肺潜水呼吸气瓶、外科部件和汽车工业。通过这种方法，铝合金制成的复杂结构可以在一个装置中生产，公差非常小。本研究探讨了AA6061的WEDM，以优化不同的工艺变量，从而获得最大MRR和最小SR的性能指标。田口的L18 OA矩阵、s/N比、ANOVA和灰色关联分析用于优化SR和MRR。方差分析表明，脉冲导通时间和峰值电流是对MRR和SR影响最大的方面，它们的贡献分别为13.33%和16.25%。此外，通过对MRR和SR应用GRA，确定了可能考虑的最佳参数设置，即脉冲开启时间50µs、脉冲关闭时间13µs和峰值电流-4安培。

Investigation of aluminum alloy 6061 in Wire-EDM regarding surface roughness and material removal rate by adopting optimization techniques

Wire-electric discharge machining offers a number of benefits in comparison to traditional manufacturing processes likewise, no obvious mechanical cutting traces also hard and rigid materials can be processed perfectly in WEDM. Since, aluminum alloys are used in aerospace, shipbuilding, breathing gas cylinders for scuba diving, surgical components and automotive industry for their high-strength-to-weight ratio, accurate shapes and dimensions. Through this method, complicated structures made of aluminum alloy are produced in a single setup with incredibly tight tolerances. The present investigation explores WEDM for AA6061 to optimize different process variables for attaining performance measures in terms of maximum MRR and minimum SR. Taguchi’s L18 OA matrix, S/N ratio, ANOVA and Grey Relational Analysis were employed to optimize SR and MRR. It has been noted from ANOVA that pulse on time and peak current are the most influential aspects for MRR and SR with their contributions of 13.33% and 16.25% respectively. Further, the best possible considered parameters setting has been established by applying GRA for MRR and SR are, pulse on time-50µs, pulse off time-13µs and peak current-4 amp.

期刊介绍： The Journal of Mechanical Engineering & Sciences "JMES" (ISSN (Print): 2289-4659; e-ISSN: 2231-8380) is an open access peer-review journal (Indexed by Emerging Source Citation Index (ESCI), WOS; SCOPUS Index (Elsevier); EBSCOhost; Index Copernicus; Ulrichsweb, DOAJ, Google Scholar) which publishes original and review articles that advance the understanding of both the fundamentals of engineering science and its application to the solution of challenges and problems in mechanical engineering systems, machines and components. It is particularly concerned with the demonstration of engineering science solutions to specific industrial problems. Original contributions providing insight into the use of analytical, computational modeling, structural mechanics, metal forming, behavior and application of advanced materials, impact mechanics, strain localization and other effects of nonlinearity, fluid mechanics, robotics, tribology, thermodynamics, and materials processing generally from the core of the journal contents are encouraged. Only original, innovative and novel papers will be considered for publication in the JMES. The authors are required to confirm that their paper has not been submitted to any other journal in English or any other language. The JMES welcome contributions from all who wishes to report on new developments and latest findings in mechanical engineering.
