Abstract:
In a study aimed at optimizing wear mechanisms in the dry turning process of AISI410 stainless steel, the effects of spindle velocity, cutting depth, surface roughness, and cutting resistance were investigated for uncoated and PVD-coated multi-layer TiAlN and TiN/TiAlN tools. The experiment utilized an L27 orthogonal array, suitable for experiments with limited runs, and three levels of feed rate, spindle speed, and cutting depth. The Taguchi method, a statistical approach to process optimization, was employed to identify influential factors and their optimal levels. Results showed that spindle velocity had the most significant impact on surface roughness and cutting resistance, followed by the type of coating, spindle speed, feed rate, and cutting depth. Spindle velocity accounted for 27.07% of the variation in surface roughness, while the type of coating contributed 19.62%. For wear rate, the TiN/TiAlN coating had the most substantial influence, contributing 60.74%. By using the Taguchi method to identify optimal machining settings, improvements can be made in quality and productivity, reducing process variability and enhancing overall performance.
