Abstract

The paper presents the problem of the correct selection of the cutting clearance during the cutting process of aluminum alloys on circular shears. Currently, production lines lack correct guidelines on how to set the cutting clearance depending on the type of aluminum alloy and its thickness. This causes defects in the products and accelerated wear of the cutting tools.The paper presents the results of experimental and numerical research related to the process of shear-slitting of t = 1 mm AA6111-T4 aluminum alloy. During the experimental studies, it was determined how the value of the clearance affects the characteristic features of the cut edge and deviations of the shape of the product. Using numerical tests, the influence of the clearance value on the stress values in the cutting zone was determined. For the AA6111-T4 aluminum alloy, the highest product quality was obtained using clearances hc = 0.09 mm and hc = 0.12 mm. The conducted experimental research can be useful on production lines in the aspect of the correct selection of technological parameters of the process due to the adopted energy and quality criteria.

剪切-切削过程中的切削间隙对 AA6111-T4 铝合金残余应力和切削表面质量的影响

本文介绍了在圆剪上切割铝合金过程中正确选择切割间隙的问题。目前，生产线缺乏关于如何根据铝合金类型和厚度设置切削间隙的正确指导。本文介绍了与 t = 1 mm AA6111-T4 铝合金剪切分切过程相关的实验和数值研究结果。在实验研究中，确定了间隙值如何影响切削刃的特征和产品形状的偏差。通过数值测试，确定了间隙值对切削区应力值的影响。对于 AA6111-T4 铝合金，使用间隙 hc = 0.09 毫米和 hc = 0.12 毫米可获得最高的产品质量。根据所采用的能量和质量标准，所进行的实验研究对生产线正确选择工艺参数很有帮助。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
