N2 - A surface grinding process is a dynamic and complex machining process. This process was used in manufacturing products that require hight tolerance, high precision and shigh surface quality of workpieces. Therefore, the selection of abrasive types and parameters of surface grinding processes (speed ratio and grit size) can give an impact on the increasing vibration level and surface roughness. Thus, the main goal of this study is to analyze the effect of speed ratio and grit size on vibration level and surface roughness. This research was conducted on a surface grinding machine using a type of aluminum oxide grinding wheel, on six variations speed ratio of four grit size variations and two variations depth of cut. The workpiece material being grinded is hardened OCR12VM up more than to 58 HRC with dimensions of 300 mm x 60 mm x 20 mm. The vibration level measurement is performed by ADC Picoscope 4262 and the surface roughness by using surftest mitutoyo-301. The conclusion of this study is that the greater the speed ratio, the vibration level will be smaller and proportional to the surface roughness. Likewise, with the finer grit size, the resulting vibration level became lower and also the surface roughness.
