INVESTIGATION OF SURFACE ROUGHNESS CHARACTERISTICS OF FACE MILLING
Keywords:face milling, cutting forces, depth of cut, cutting speed, rectangular inserts.
AbstractSurface quality and accuracy affect the integrity and lifetime of machine parts and the operational requirements of the structural (or assembly) units. These are the reasons that the expected surface roughness must be planned based on the operational requirements of the parts. The path of the tool edge, which is defined by the characteristics of the kinematics of face milling, makes the milled surface inhomogeneous, which means the roughness analysis in various directions gives different values. In this paper the effect of increasing the feed rate on surface roughness is investigated. This cutting data is chosen because increasing the feed rate is an effective way to increase productivity.
