Geometric Model of Height of Microroughness on Machined Surface Taking into Account Wear of Face Mill Teeth

摘要

The present paper describes a geometric model of the height of microroughness on the machined flat surface after the face milling with the account of wear of tools. The model takes into account the height variations of microroughness on the flat surface due to the dimensional wear of the radius portion of apexes of face mill teeth. The work resulted in the findings of the height of microroughness at different feeds, rounding radii, different front and back angles of the mill tooth taking into account the wear of tools over the tailing surface.
