    (2018) Ic, Yusuf Tansel; Gunay, Ezgi; Yurdakul, Mustafa; Mizrak, Haci Veli; Gunes, Serkan; AAI-1081-2020
    In this study, it is aimed to experimentally optimize the parameters of the grinding of external surface of the roller followers which are used in internal combustion engines to operate the inlet and exhaust valves. 2k factorial experimental design methodology is applied to optimize the grinding process such that after this last finishing operation the rollers' external surface quality and cycle time meets the customers' special and strict requirements. In the application of the experimental design methodology, the critical parameters that are important in the optimization of two different surface roughness values along with cycle time are first determined. Then, the values of critical parameters are calculated with the application of the multi-objective optimization of the two surface roughness measures and cycle time. As a result of the optimization, the surface roughness values that are important in the working of the roller followers and cycle time are improved.
