-
Tool runout has a significant influence of the surface roughness, and axial tool runout limits the achievable surface roughness. Three typical surface topography generation cases of the machined surface in micro milling are presented by considering tool runout, and the emergence conditions for each surface generation cases are investigated quantitatively.
-
The tool runout in axial direction has significant influence on the machined topography generation.
-
Proposed surface generation model has been verified by the micro milling experiments over a wide range of feedrate, and the results show that it provides accurate surface topography prediction.
