Cr-Mo강의 비연삭에너지 특성 = Analysis of Specific grinding characteristics

다국어 초록 (Multilingual Abstract)

In this study, series of grinding tests have been carried out on Cr-Mo steel workpieces. The workpieces were prepared for different hardness levels through different heat treating processes. In grinding tests, WA and CBN wheels of different grain size were used with varying conditions of cutting depth and workpieces velocity. Experimental results show that the specific grinding energy decreases as the maximum undeformed chip thickness increases regardless of hardness of workpieces and type of wheel used.
Less specific energy is consumed in the case of smaller abrasive grain size of same kind and with workpieces of intermediate hardness. The energy efficiency of CBN wheel is less than that of WA wheel.
