Abstract:
To investigate the research directions and advancements in domestic dynamic vibration-absorbing cutting tools, vibrations in metal cutting processes and damping methods were summarized. Based on the principle of undamped dynamic vibration absorption, the fixed-point theory, optimal tuning, and optimal damping of vibration absorption technology were elaborated. The extended fixed-point theory and mass induction method were introduced, followed by a summary of current research on three key factors of dynamic vibration absorbers, namely mass, stiffness, and damping. Discussions were conducted on dual and multiple dynamic vibration absorbers, active dynamic vibration absorbers, and hybrid dynamic vibration absorbers. Examples of dynamic vibration-absorbing tools from internationally renowned tool manufacturers and domestic deep-hole machining vibration absorbers were listed. The establishment of a scientific and comprehensive database for vibration-absorbing tools was proposed to meet industry demands. It is suggested that intelligent extraction of vibration characteristics through deep learning and adaptive control of active and hybrid dynamic vibration-absorbing tool holders represent key research directions for smart manufacturing.
