Abstract
A rounded nose end-mill modified by optimization of geometrical parameters of both the rake angle and relief angle along the cutting edge of the rounded portion, wherein the rake angle and the relief angle gradually increase along the cutting edge from the full diameter of the rounded portion to the tip.
Claims14
A rounded nose end-mill comprising:
- a shank having a rounded cutting portion disposed at an end thereof, the shank having an outer diameter, the rounded cutting portion including at least one rounded cutting edge extending from the outer diameter toward a tip of the shank and having a rake angle and a relief angle,
- wherein the rake angle is non-negative and gradually increases, without decrease, along the rounded cutting edge from the outside diameter to the tip, and
- wherein the relief angle gradually increases along the rounded cutting edge from the outer diameter to the tip.
