Computational Investigation of Chatter for Face Mill Tool on VMC Using Different Shim Material with Experimental Validation

Optimization of vibration amplitude ratio of face mill tool of VMC and analysis with design expert to endorsing shim design

“…Machining has noise and chatter is a major problem as VMC-vertical milling Centre causes more vibrations at maximum speed operation (Celikag et al, 2019;Yuan et al, 2019). Today accuracy and precision with top speed machining is important to scratch price and escalation production (Gandhi and Pandya, 2022). One of the biggest obstacles to fully automating machining processes including milling, drilling, boring, and turning is chatter (Eynian, 2019;Gandhi and Pandya 2022).…”

One of the biggest obstacles to fully automating machining processes including milling, drilling, boring, and turning is chatter (Eynian, 2019;Gandhi and Pandya 2022). Chatter in machining causes issues like poor surface smoothness, excessive noise, shorter tool life, and in the worst scenario, component breakdown, which lowers productivity (Yue et al, 2018;Liu et al, 2019;Wenish et al, 2019;Prajapati et al, 2020).…”

“…Face milling is the most common milling process and can be accomplished using various wide range of different tools. Here Special Purpose two types of face mill with (TNMG) inserts, diameter Ø63mm and 5 inserts without shim and with shim is discussed (Gandhi and Pandya, 2022). Gandhi and Pandya (2022) had conducted computational analysis of the face mill tool utilizing the carbide shim, the SS-Stainless Steel shim, and the without shim face mill tool, followed by a harmonic analysis.…”

Gandhi and Pandya (2022) had conducted computational analysis of the face mill tool utilizing the carbide shim, the SS-Stainless Steel shim, and the without shim face mill tool, followed by a harmonic analysis. The ANSYS workbench was used for computational analysis (FEA), and the calculated damping ratio was validated by experimental analysis for decreasing chatter by examining the operational and stationary properties of the cutting tools.…”

“…Our objective is to decrease chatter and to improve surface quality in VMC-Vertical Milling Centre (Gandhi and Pandya, 2022). An aim of research is not only to reduce chatter by using shim but also validates with ANOVA and makes it versatile and proven by optimization (Ambigai and Prabhu, 2019).…”
