Abstract

This paper represents the results of research on effects of process parameters on vibration in surface processing high level hardness materials with segmented grinding wheel using Taguchi method and Analysis of Variance (ANOVA). This method reduces the number of experiments, produces high quality products with low cost for manufacturers. With three experiments, three testing and three replications of the design point, the research results showed the relationship between technological parameters which are cutting depth, feed rate and the number of grinding slots with the pair interactions, and three interactions between them with the vibration, and identified locally optimal technological and systematic parameters with the smallest vibration in surface grinding on SKD11 steel under heat treatment by intermittent grinding stone made in Vietnam
