“…They also mentioned that damping was simple in construction, low cost, robust and able to work in harsh environments. Similar work was reported in [26] where they used spring damper in the boring process. Thus, passive damping approach may play a key role in vibration isolation in the machining process.…”

In ultrasonic vibration-assisted turning (UVAT), vibration is one of the critical factors that causes noise during machining and affects cutting tool life, machining accuracy and workpiece surface quality. Vibration generated by piezoelectric actuators tends to transmit undesired vibration on the edge of the cutting tool and tool post. This situation hinders the maximization of vibration energy usage in the cutting tool. Thus, this paper investigated the vibration performance in the cutting tool by adding an isolator pad as damping element in the static zone of a tool holder to reduce the resonance generated during the machining process. The static, vibration and surface roughness analysis has been performed to determine the impact of damping on the machining performance. The results revealed a significant improvement in surface roughness where the best Ra for UVAT was 0.38 μm. In addition, vibration and static analysis showed the application of isolator pad capable of reducing 80% of energy loses and a supporter to increase the displacement, respectively. Ultimately this innovative solution can play an important role in improving UVAT performance.

“…In the manufacturing sector, the boring process is used to enlarge the pre-drilled or cast holes, and its operation was found to be difficult when compared with external turning process. During the machining process, the length of boring bar will be kept long, which resulted in excessive vibration, tool failure, higher cutting force and temperature (Lawrance et al, 2017). Nowadays, because of the advancement in technology, the metal cutting industry is focused towards attaining quality product, increase in production rate and cost-effective machining with reduced environmental impact (Lawrance et al, 2019).…”

Purpose In the internal turning process, tool life and work piece quality are greatly influenced by the generation of heat in the cutting zone. During machining, cutting fluids are applied at the cutting zones to reduce heat generation and enhance tribological properties. However, in the boring process, cutting fluids cannot be applied at cutting zone properly, and wastage of cutting fluid is a threat to the ecology and personnel health. Hence, application of semisolid lubricant in the boring process is considered as an innovative technique for temperature reduction in cutting zone because of its eco-friendly system, which also has a higher ability of biodegradability. This paper aims to study the influence of semisolid lubricants comprising of grease,graphite, aluminium oxide in different composition applied at a tool–chip,tool–work interface using a semisolid lubricant applicator applied with varying pressure. Design/methodology/approach In the present study, the cutting performance during boring of AISI4340 steel is enhanced through the application of semisolid lubricant with different composition of grease, graphite and aluminium oxide applied at tool-work and tool-chip interface with varying pressure using semisolid lubricant applicator. Findings The results show that use of semisolid lubricant like grease, graphite and nano aluminium oxide at tool-chip interface with maximum pressure reduces cutting temperature, tool vibration, cutting force and surface roughness. Originality/value Reduce cutting temperature, tool vibration, cutting force and surface roughness.

“…The metal cutting industries is motivated towards high standard product and increased manufacturing. In manufacturing sector, the relative movement between metal cutting process and dynamics of machine tool leads to tool vibration (Lawrance et al, 2017). The overhanging length of the boring tool is a major reason for an enhanced tool vibration which results in high surface roughness and reduced tool life .…”

Tool vibration is the most unfavourable element in the boring operation, as it contributes to poor surface finish, excessive tool wear, and progressive cutting force. Tool vibration mainly occurs due to the overhanging length of the boring tool and to overcome this factor an appropriate mechanism has to be established which helps to increase the production and quality of the product in manufacturing sector. An impact particle damper with variable material spheres, sphere diameter, and sphere location in a boring tool is fabricated in this work. A 27 run experiments were conducted to find the effect of impact particle damping on tribological properties during boring process. The results shows that impact particle damper increases the rigidity of the tool holder which enhances the tribological properties. The sphere in the boring tool will collide with one another thereby suppressing the tool vibration efficiently.
