Vertical Path Strategy for 3D-Cad Analysis of Chip Area in 3-Axes Ball Nose End Milling

Abstract

Abstract: Vertical cutter path orientations strategy is investigated and evaluated in this 3D-CAD study, for the chip area, in upward and downward feed directions of ball nose end mill, for different workpiece inclination angle. A minimum workpiece inclination angle to avoid cutting at the tip of the cutter is defined such the angle between cutter axis and surface normal. The result of analysis between the chip area and the inclination angle has been shown in graphics, for one cutting edge rotation. The cutting force on the tool edge is in proportion with the chip area and using this study, can be predicted the inclination angle and direction of milling to improve the cutting performance
