The present work deals with comparative study on cutting performance of plain carbide and coated carbide inserts in turning of EN9 steel. The design of experiments (DOE) was done using response surface methodology (RSM) technique. The cutting parameters were spindle speed, feed and depth of cut (DOC). The combined interactions of cutting parameters on surface roughness, flank wear and crater wear were analyzed. The crater and flank wear were observed using machine vision system. This work is concentrated on building up a mathematical relation between cutting parameters and output responses. Analysis of variance (ANOVA) was used for checking the adequacy of the model. The relation between input factors and the response parameters are determined using a cubic regression model. The optimization was done using desirability ramp plots. The main motive behind this research is to compare the performance of plain and coated carbide tool and analyzing which tool performs better and to op...

EN9钢CNC车削中普通和涂层硬质合金刀片切削性能的比较研究。

目前的工作是对EN9钢车削中的普通硬质合金和涂层硬质合金刀片的切削性能进行比较研究。实验设计（DOE）使用响应面方法（RSM）技术完成。切削参数为主轴转速，进给和切削深度（DOC）。分析了切削参数对表面粗糙度，后刀面磨损和月牙洼磨损的综合相互作用。使用机器视觉系统观察到的火山口和侧面磨损。这项工作集中在建立切削参数和输出响应之间的数学关系上。方差分析（ANOVA）用于检查模型的适当性。使用三次回归模型确定输入因子与响应参数之间的关系。使用期望斜率图完成了优化。
