Title : Effects of Dressing Parameters on Material Removal Rate in Grinding of Hardened SKD11 Alloy Steel using CBN Wheel

Abstract :

In the grinding process, the dressing plays a vital role in ensuring the topography and performance of the grinding wheel. This study examines the effect of some critical parameters of dressing on material removal rate in grinding SKD 11 alloy steel using CBN wheels. The Taguchi method is used to organize experiments as well as provide statistical analysis. The dressing parameters chosen are the dressing depth, the dressing spindle speed, and the dressing feed rate. The CBN grinding wheel was dressed in a condition with three levels of the dressing depth (from 0.01 to 0.03 mm), three levels of the dressing spindle speed (from 500 to 2000 rpm), and three levels of the dressing feed rate (from 100 to 800 mm/min). The optimum conditions of the dressing have been achieved for the maximum material removal rates. Along with that, an analysis of variance (ANOVA) was performed to assess the appropriateness of the empirical model. The results show that the dressing spindle speed is the parameter that has the greatest influence on MRR, followed by the dressing depth.
