Abstract

Present study shows the effects that form the significantly different microgeometry and surface roughness parameters compare to the theoretical surface in case of cutting processes with multi-blade cutting tools. Based on experimental tests the development of surface roughness is presented in case of drilling, face-and plain milling processes. It is proved that the production inaccuracy (run-out) of applied tools and the tool wear and cutting edge degradation in cutting processes causes amplitude, average and form deviation on machined microgeometry during the surface formation. It is pointed that the run-out of tool holder shaft-beside the cutting parameters and geometry-also plays significant role in formation of surface roughness.
