On April 28, the Intelligent Manufacturing Control & Equipment Research Center published online its latest review entitled A review of robotic machining dynamics: A new perspective based on multi-source compliance in International Journal of Machine Tools and Manufacture (IJMTM), a top-tier journal in the manufacturing field. IJMTM has an impact factor of 18.8 and publishes only over 50 articles annually. Dr. Shihao Xin, a postdoctoral researcher at our school, is the first author of the paper, and Professors Fangyu Peng and Xiaowei Tang are the co-corresponding authors. IJMTM is widely recognized as the leading journal in the manufacturing field, with an immediate impact factor reaching 24.04 as of May 6. This review marks the first review paper in the field of robotic machining dynamics ever published in IJMTM.
Research on robotic machining dynamics is a critical prerequisite for achieving efficient and stable robotic machining. However, for a long time, most studies in this field have followed the research paradigm of machine tool machining dynamics. While the well-established research system of machine tool machining dynamics has provided valuable insights and methodologies for robotic machining dynamics research, it has also constrained researchers' insight and innovative thinking. A large number of studies have merely treated robots as another type of machine tool, lacking in-depth exploration of the unique characteristics inherent to robotic milling systems.
The research team identified the multi-source compliance characteristics of robotic machining systems—high-frequency compliance at the tool end and low-frequency compliance at the robot end. They conducted a comprehensive summary and review of relevant studies on dynamic characteristics, stability, and vibration suppression in the field of robotic machining dynamics, explored the classification method for machining stability research from the multi-source compliance perspective, which provides a reference for reconciling the long-standing controversy in the field regarding the causes of low-frequency chatter at high spindle speeds. Finally, they summarized the existing challenges in robotic machining dynamics research and outlined future development directions. This paper aims to establish a research framework that embodies the unique characteristics of robotic milling systems, clarify the research context for potential researchers, provide referenceable future research directions, and accelerate the development of robotic machining dynamics and the practical implementation of its engineering applications.
