The Effect of Axial Cutting Edge Angle on the Axial Milling Force of Helical Milling

Abstract:

For decreasing axial milling force in helical milling and improving machining quality, researches have been carried out on end mills’ geometrical parameters. And experiments have also been designed to analyze the effect of end mill’s axial cutting edge angle on axial milling force. The results indicate that when other mills’ geometrical and process parameters are constant, the generated mean axial milling force is remarkably decreased, following the axial cutting edge angle’s little increase. In addition, as the pitch of helical milling path increases, larger axial cutting edge angle leads to higher relative decrease ratio. And a qualitative analysis is also put up to point out the reason for the phenomena above, that is, part of the low-speed region of axial cutting edge quits milling. These conclusions could supply valuable references to reasonable choice of combinations of mills’ geometrical and process parameters in helical milling.
