Cylindrical grinding operation is an important metal cutting process used as a finish process to achieve the surface quality and dimensional stability of the products. In this context, experimental work and statistical analysis in researches contribute to improve product quality of manufactured parts. Tempered steels are widely used for automotive components and manufacturing applications. The objective of this study is to analyze the surface roughness (Ra) values of cryogenically (cryo) treated and tempered steels in cylindrical grinding operation. According to the grinding experiments created by the Taguchi method, grinding wheels (Al₂O₃ and SiC), heat treated steel samples (HT, CT24, and CT36) and depth of cut (50, 100, and 150μm) were selected to determine the optimum surface roughness values of these steels. The results showed that significant improvements in Ra values of cryo-treated and tempered steels were observed. The lowest Ra values were obtained in cryo-treated sample (CT36) with SiC grinding wheel and depth of cut (50μm).

外圆磨削加工中低温调质钢的表面粗糙度分析

外圆磨削操作是一种重要的金属切削加工工艺，用作精加工工艺，以达到产品的表面质量和尺寸稳定性。在这种情况下，研究中的实验工作和统计分析有助于提高制造零件的产品质量。回火钢广泛用于汽车部件和制造应用。本研究的目的是分析表面粗糙度（拉) 外圆磨削操作中低温 (cryo) 处理和回火钢的值。根据田口法创建的磨削实验，砂轮（Al ₂ O ₃和 SiC）、热处理钢样品（HT、CT24 和 CT36）和切削深度（50、100 和 150μm) 用于确定这些钢的最佳表面粗糙度值。结果表明，显着改善拉观察了低温处理和回火钢的值。最低的拉使用 SiC 砂轮和切削深度（50μ米）。
