Abstract
The paper brings the results of surface finish analysis of formed parts produced by CNC multi-pass conventional metal spinning. The influence of mandrel speed, spinning roller feed and workpiece geometry on the surface finish of formed parts made of mild steel type of EN 10025-94 (ISO 630-80) have been studied by profile and 3D surface parameters evaluating. For the study, the full factorial design of experiment (33) was used and ANOVA (Analysis of Variance) was carried out. It is shown that the optimal roller feed exists within the range of minimal and maximal experimental feed values and the surface roughness measured in different areas of experimental samples (radius R10, conical area, cylindrical area) indicates that the higher surface roughness occurs at the conical surfaces.
