This article represents the result of a research on the impact of cutting parameters including the number of segments, cutting depth and feed rate on cutting force P in grinding hardened steel SKD11 using segmented grinding wheel by Taguchi method and analysis of variance (ANOVA). The result released the information of the relationship between the number of segments, cutting depth and feed rate and its interactions with cutting force. Local optimal value of cutting force can also be determined with minimal cutting force and low surface roughness when machining the SKD11 harden steel using segmented grinding wheel. Keywords: cutting force, Taguchi method, ANOVA, cutting depth, surface grinding. 1. INTRODUTION Grinding force caused the elastic deformation of the technology system, vibration and thermal in cutting areas. It is also used to determine the mode of grinding wheel wear. When shear stress increases, the grinding wheel’s life reduces, reduced machining accuracy and surface roughness increases. In particular, the immediate change of the shear is the main reason causing the vibration of the wheel and other types of errors [1,2]. Julie Z. Zhang [3] and Taranveer Singh [4] and colleagues used the Taguchi method to find the optimal process parameters. Some authors in Vietnam, [5] and [6], studied the influence of some .
