Determination of Optimum Tilting Angle of Ball-End Mill in 5-Axis Control Machining. In the Case of Spherical Surface Machining Based on Finished Surface Roughness
Journal of the Japan Society for Precision Engineering
When machining a spherical surface along a contour line with a ball-end mill at high feed speed, the finished surface roughness is greatly affected by the tilting angle of the tool axis. In order to obtain fine surface roughness, this paper proposes concepts of optimum tilting angle and minimum surface roughness for spherical surface machining. The computer simulation demonstrates that the surface roughness can be dramatically improved by tilting the tool axis with an optimum tilting angle, asdoi:10.2493/jjspe.63.992 fatcat:5i76mv77jfa5tg3jiaek5uxb2e
