Effects of Time Delay on Manufacturing

Manufacturing effectiveness has the potential for significant growth, yet its progress is impeded by the dynamics of the manufacturing processes. Specifically, the material removal rate (MRR) in machining processes experiences a reduction to avoid chatter. Consequently, the anticipation and management of chatter have emerged as prominent subjects over the last two decades. Cutting instabilities have frictional, regenerative, mode-coupling, and thermo-mechanical types, where the primary (frictional) and secondary (regenerative) are the most significant ones (Wiercigroch and Budak in Philosoph Trans R Soc Lond Ser A Math Phys Eng Sci 359(1781):663–93, [1]). These groups have extensively investigated self-excited chatter within turning (Fu et al. in Int J Mech Sci 88:145–153, [2]) and other manufacturing processes.
