SINGLE POINT CUTTING TOOL NOMENCLATURE ANALYSIS IN THE TURNING PROCESS FOR SURFACE QUALITY
Abstract
Generally machining operations are used to produce a desired shape and size by removing excess stock from a blank in the form of chips. New surfaces are generated through a process of plastic deformation and crack propagation. The workpiece is subjected to intense mechanical stresses and localized heating by tools having one or more shaped cutting edges. Each cutting edge leaves its own mark on the machined surface. Also the workpiece and tool, together with the machine on which they are mounted, form a vibratory system liable to random, forced are induced vibrations. These vibrations alter the relative distances between the tool and the workpiece and hence damage the surface quality as well as dimension of the component.From the literature survey, it is found that most affecting parameters for surface quality of the components are rack angles, cutting edge angles, relief angles and nose radius. Considering the above, this paper proposes Design of Experiments concepts for analyzing effect of back rack angle, side rack angle, side relief angle and nose radius on surface quality of turned aluminum components in a CNC trainer Lathe. Design of experiments  is a powerful tool that can be used to manipulate multiple input factors to show their effect on a desired output (response). The orthogonal Array a powerful tool of DOE is chosen for analysis
