摘要

自激颤振是影响切削效率降低的因素之一，特别是在加工高度柔顺的机械零件时。它们的发生可以通过适当的工艺参数选择来限制。这些参数可以通过分析切削过程的稳定性来确定，这需要了解机床工件系统的动态特性。通常，这些性质是通过实验来确定的，这在工业实践中是很麻烦的。本文介绍了一种由集成了数控系统的单板计算机计算动态特性的方法，而不需要进行额外的实验测试。采用接收耦合方法可以通过分析加工程序获得工件的几何形状，然后确定机床-工件系统的动态特性。这些特性是所提出的算法的输入，该算法有助于选择切削参数，从而实现高度顺应的机器零件的稳定车削。提出的系统是专用于车削，但也可以适应于确定铣削与柔性刀具的稳定性。©2020 CPE，马里博尔大学。版权所有。

An integrated CNC system for chatter suppression in turning

Self‐excited chatter vibrations are one of factors affecting the reduction of cutting efficiency, especially while machining highly compliant machine parts. Their occurrence can be limited by the proper technological parameters selec‐ tion. These parameters can be determined by analysing the cutting process stability, which requires knowledge of the machine‐tool‐workpiece system dynamic properties. Normally, these properties are determined experimental‐ ly, which is troublesome in industrial practice. This article presents a method in which dynamic properties are calculated by single‐board computer inte‐ grated with a Computer Numerical Control (CNC) system, with no need to carry out additional experimental tests. It is possible with the receptance coupling approach which allows for obtaining the workpiece geometry by analyzing the machining program and then determining the machine tool – workpiece system dynamic properties. These properties are the input to the presented algorithm that facilitates the selection of cutting parameters ena‐ bling stable turning of highly compliant machine parts. The presented system is dedicated to turning but can also be adapted to determine the stability of milling with flexible tools. © 2020 CPE, University of Maribor. All rights reserved.

期刊介绍： Advances in Production Engineering & Management (APEM journal) is an interdisciplinary international academic journal published quarterly. The main goal of the APEM journal is to present original, high quality, theoretical and application-oriented research developments in all areas of production engineering and production management to a broad audience of academics and practitioners. In order to bridge the gap between theory and practice, applications based on advanced theory and case studies are particularly welcome. For theoretical papers, their originality and research contributions are the main factors in the evaluation process. General approaches, formalisms, algorithms or techniques should be illustrated with significant applications that demonstrate their applicability to real-world problems. Please note the APEM journal is not intended especially for studying problems in the finance, economics, business, and bank sectors even though the methodology in the paper is quality/project management oriented. Therefore, the papers should include a substantial level of engineering issues in the field of manufacturing engineering.
