Abstract

Turn-milling is a machining method with a system of merging turning and milling operations, which the workpieces and cutting tool perform rotary motion synchronously to optimize the disposal process of chip materials. Development of turn-milling can be done on the lathe and milling conventional machining. The purpose of this study is to modify a conventional lathe with a stationary cutting tool and use a single cutting edge into a rotary tool using 4 (four) cutting sides (multy point cutting). In the manufacture and installation of rotary tool on conventional lathes, tools are made portable and can work on tangential, orthogonal and co-axial turn-milling systems. For the orthogonal and co-axial operating system of the turn-milling are divided into up and down operating systems. In this research the phenomenon of material disposal process of the work-piece surface was investigated. In the process of turn-milling test, the chip was removed automatically as the turn of the cutting edge of the endmill cutting tool. The high decreasing of cutting knife rotation during testing was resulted a space during the process of disposal of material. Sequence, it was occurred pores or cavities in the work-piece.

Abstract

The surface roughness of a machining process is a very important factor in the field of production that is one of the turn-milling process. Turn-milling is a combined machining process of turning and milling with complete tools (cutting) where workpieces and tools rotate together. The turn-milling process can generally be categorized in orthogonal turn-milling, tangential turn-milling and co-axial turn-milling methods. The resulting surface quality is also affected by the parameters of the machining process in the form of rotation of the workpiece and the rotation of the tool. The purpose of this research is to know the effect of parameters on surface roughness and optimal parameter to surface roughness by doing tangential process of turn-milling. By varying the parameter variables, the surface roughness generated in this study is influenced by the rotation of the workpiece and the rotation of the tool. The higher the tool rotation the lower the surface roughness. Conversely, the higher the rotation of the workpiece the higher the surface roughness. The optimal parameter is a rotation tool of 25000 rpm with a rotation of 630 rpm objects found in the roughness class N7 with a roughness value of 1.321 μm where the roughness value is lower among other N7 roughness classes.Keywords : Turn-milling, Tangential Turn-milling, Rotation, Roughness.
