Development of mathematical model for chip serration frequency in turning of stainless steel 304 using RSM by Amin, A. K. M. Nurul, Sulaiman, Syidatul Akma, Arif, Muammer Din

“…Avoidance of chatter has mostly been through reliance on heuristics such as: limiting material removal rates (to stay within the dynamic stability boundary) or selecting low spindle speeds and shallow depth of cuts. However, the correct understanding of the mechanism of chatter formation in metal cutting reveals that chip morphology and segmentation play a predominant role in chatter formation during machining. …”

Statistical approach to modeling & optimization of surface roughness in high speed end milling of silicon with diamond coated tools by Amin, A. K. M. Nurul, Khalid, Noor Syairah, Mohd Nasir, Siti Nurshahida, Arif, Muammer Din

“…This research demonstrated the use of conventional milling machines with diamond coated tools, high speed attachments, and air blowing mechanisms for ductile mode machining of silicon and subsequently modeling and optimizing the resultant surface roughness. Spindle speed, depth of cut, and feed rate, ranges: 60,000 to 80,000 rpm, 10 to 20 μm, and 5 to 15 mm/min respectively, were considered as the independent machining parameters for the modeling process. …”
