摘要

复杂系统小型化的需求日益增加，需要生产更小的部件，切割具有精密的尺寸精度。此外，线切割电火花加工(WEDM)工艺以其精度，获得复杂形状的可能性，紧密的公差和经济的优势在快速发展的行业中占有突出地位。因此，本实验工作的目的是分析脉冲时间和送丝速度对性能特性，即切口宽度和热影响区(HAZ)的影响。采用响应面设计方法，对厚度为2mm的铝板进行了电火花线切割微水平槽切实验。多准则决策采用灰色关联分析(GRA)技术寻找工艺约束的最优机器设置。建立了输出约束的多项式模型。结果表明，脉冲导通时间对切口宽度的影响更大，而送丝速度对热影响区影响更大。所获得的成果将加速先进加工行业提高可加工性和尺寸精度。

Experimental analysis of Aluminum alloy 8011 using Wire cut Electrical discharge machining

The increased demand for miniaturization of complex systems necessitates the production of smaller components, cutting with precision dimensional accuracy. Furthermore, Wire cut electrical discharge machining (WEDM) process is the prominent to the fastest growing industries because of their accuracy, the possibility to obtain complex shapes, close tolerances and economically. Therefore, the aim of this experimental work is to analyze the impact of pulse on time and wire feed rate on performance characteristics namely, kerf width and heat affected zone (HAZ). In this experimental investigation, micro level slot cutting experiments were carried out on aluminum plate of 2 mm thickness by WEDM with response surface design. Multi-criteria decision making Grey relational analysis (GRA) technique has been utilized to find optimal machine settings of process constraints. Polynomial models were developed for output constraints. From results, it is analyzed that the pulse on time has more dominance on kerf width, whereas the wire feed rate has a higher influence on HAZ. The obtained outcomes will expedite the advanced machining industries to enhance machinability and dimensional accuracy.

期刊介绍： Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas. Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards. The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests. Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events. All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge. Neither the INTERCIENCIA Association, nor the journal or the institutions to which the authors belong carry responsibility for the contents. Signing authors are responsible for the material published under their names.
