“…Marui et al [112] incorporated a friction plate within the overhanging part of the tool shank in order to improve the damping capacity of the system by friction during vibration acting between the inner wall of the hole and the inserted plate surface. However, the extent of damping capacity improvement is affected by the position of the hole and the interference between the rectangular hole and the inserted plate.…”

“…These methods can be classified as passive, active and semi-active methods. Normally, friction plates were used to dampen vibration with the help of attaching it with a tool shank and taking advantage of friction produced (Marui et al, 1998). Tuned mass dampers were used in many cases as a passive vibration technique (Hartog, 1985).…”

Purpose A new cutting tool is always well-defined and sharp at the onset of the metal cutting process and gradually losses these properties as the machining process advances. Similarly, at the beginning of the machining process, amplitude of tool vibrations is considerably low and it increases gradually and peaks at the end of the service period of the cutting tool while machining. It is significant to provide a corresponding real-time varying damping to control this chatter, which directly influences accuracy and quality of productivity. This paper aims to review the literature related to the application of smart fluid to control vibration in metal cutting and also focused on the challenges involved in the implementation of active control system during machining process. Design/methodology/approach Smart dampers, which are used as semi-active and active dampers in metal cutting, were reviewed and the research studies carried out in the field of the magnetorheological (MR) damper were concentrated. In smart materials, MR fluids possess some disadvantages because of their sedimentation of iron particles, leakage and slow response time. To overcome these drawbacks, new MR materials such as MR foam, MR elastomers, MR gels and MR plastomers have been recommended and suggested. This review intents to throw light into available literature which exclusively deals with controlling chatter in metal cutting with the help of MR damping methods. Findings Using an MR damper popularly known for its semi-active damping characteristics is very adaptable and flexible in controlling chatter by providing damping to real-time amplitudes of tool vibration. In the past, many researchers have attempted to implement MR damper in metal cutting to control vibration and were successful. Various methods with the help of MR fluid are illustrated. Research limitations/implications A new cutting tool is always well-defined and sharp at the onset of metal cutting process and gradually losses these properties as the machining process advances. Similarly, at the beginning of the machining process, amplitude of tool vibrations is considerably low and it increases gradually and peaks at the end of service period of cutting tool while machining. Application of MR damper along with the working methodology in metal cutting is presented, challenges met are analyzed and a scope for development is reviewed. Practical implications This study provides corresponding real-time varying damping to control tool vibration which directly influences accuracy and quality of productivity. Using an MR damper popularly known for its semi-active damping characteristics is very adaptable and flexible in controlling chatter by providing damping to real-time amplitudes of tool vibration. Social implications This study attempts to implement smart damper in metal cutting to control vibrations. Originality/value It is significant to provide corresponding real-time varying damping to control tool vibration which directly influences accuracy and quality of productivity.

“…Marui et al [6] mentioned that the damping of a tool system came from micro slide, the damping of the cutting tool itself, and the friction with the air during vibration. They therefore inserted thin sheets between cutting tool and tool slide and inside the cutting tool in order to enhance the friction force and further promote the damping of the cutting tool system.…”

Abstract. High precision and high efficiency are the essential competition conditions for multiaxis machine. However, machine vibration problems are always plagued by equipment manufacturers. This study focuses on solving or eliminating the multi-angle drilling vibration of processing machines. By the design and experiment combining CNC multi-axis machine tools with vibration tables, the surface roughness in the multi-angle drilling holes is discussed for the reference of the industry or the academia. The results indicated that adding proper vibration factors could effectively improve the bore surface roughness and smoothness. Roughness Ra with the vibration interval time 0.5 sec, could improve the surface roughness 48.95% of the processing hole, comparing to it without vibration. Besides, the resonance phenomenon disappears at the feed to generate good effect. It is expected to reduce various vibration problems faced by processing with machine tools in order to enhance the international competitiveness of processing tool manufacturers.
