In this paper there are studied the results obtained at graphite and polyvinyl chloride turning. Such pieces are used like loose parts or in subassemblies. The final roughness of such pieces after processing and the influence of processing parameters are evaluated. Thus, factorials experiments are used and non-linear relations that take into consideration the cumulated influences of two factors on roughness are obtained. The achieved results and final relations for Rz are presented. Also, microscopically images of these surfaces for different cutting workings are presented in this study.
