Abstract

If the work piece that turning very long is so whenever done by the turning machine the guy wire because crosscut style effect of crosscut chisel will generate deflexed at the work piece cause the vibration at the time of cutting process so that surface of result process bubut become harshly. To avoid that usually used the supported. On the contrary usage of supporter economically is addition of the appliance and workmanship causing at addition of production cost in industrial scale. This research wish to be known maximum limit object overhang work without using supporter of flash light turn around at lathe process. Object length work at this research reprecentaced with the length dibubut per diameter (L/D). Object examinee diameter is Ø 20 with ratio length/diameter the object turning is: 1:1, 1,5:1, 2:1, 2,5:1, 3:1, 3,5:1, 4:1. From analysis use the method test T concluded that the work piece over hang give influence of surface roughness significant otherwise used unsupported is L/D ≥ 3.
