Abstract

In metal cutting industry, edge preparation on carbide inserts have a significant effect on the productivity of a machine. In this study, the effect of various cutting edge preparations on wiper facet which influences various force components and surface finish in the rough milling operation of AISI 1070 steel were experimentally investigated. Tungsten Carbide inserts with three distinct edge preparations and AISI 1070 steel blocks were used. Three-factor (Cutting speed, Feed and Geometry), three-level full factorial design experiments were conducted under dry conditions. During the rough milling operation, three components of forces and surface finish of the machined surface were measured. This study shows that the effect of various edge geometries is more significant on surface finish and has very little impact on the force components.
