【 摘 要 】

In this study, in order to find out a mathematical relation of polynomial second degree type whichdescribe, in finish turning of hardened 205 Cr115 steel, the roughness parameter Ra dependence on cuttingedge wear, depth of cut, feed rate and cutting speed, a factorial design methodology was used. The experimentaltests were done according to a composed, central, four-factor five-level factorial program.
