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 turn-milling test has three methods in the process of working are orthogonal, tangential, and co-axial. In this methods turn-milling test produces a varied surface roughness. To optimize the surface roughness in this method orthogonal turn-milling then the variation of testing is done at the rotation velocity of workpiece and feeding velocity. The testing process of turn-milling machining is performed on conventional lathe with the addition of a rotary tool. The purpose of this research is to get the optimum rotation velocity of workpiece and feeding velocity of the value of surface roughness and To know the effect of velocity rotation of workpiece and feeding velocity to surface roughness value. With increasing velocity rotation of workpiece and feeding velocity, velocity rotation of the workpiece increased will affect the surface roughness value. Based on the roughness class N, the 630 rpm rotation of workpiece parameters with feed rate of 0.060 mm is a good parameter in this study because it produces a roughness value of 1.489 μm lower than the other test.Keywords : Turn-milling, Round, Feeding, Roughness.
