【 摘 要 】

Surface roughness is identified as an important response which is affected by the vibration of spindle and worktable. This paper is focused on the effect of machining and geometrical parameters such as spindle speed, feed rate, axial and radial depth of cut and radial rake angle on responses during end milling operation. Experiments were conducted on Aluminum alloy 6061-T6, based on Central Composite Design (CCD). Response Surface Methodology (RSM) has been used to develop the predictive models. The scanning Electron Microscopy (SEM) results indicates that the formation of surface defect on Al 6061-T6 are adhered material particles, plucking, feed marks, micro-pits and debris of microchips. Multi Objective Genetic Algorithm (MOGA) was used to predict surface roughness, amplitude of spindle and worktable vibration.
