Interaction of the workpiece material’s technological past and machining parameters on the desired quality of the product surface roughness

The paper analyzes fine turning process on workpieces with different technological past. The analysis concentrates mainly on surface roughness which is very frequently a measured quality characteristic of finished or semifinished products. We analyzed influences of workpiece material and its technological past, and machining parameters on surface roughness of machined surfaces. Statistical design and analysis of experiments was used for assessing mentioned interaction in the fine turning process.
