Embodiment
[0092] An end mill with a ring radius of 3 is selected as a design example. The detailed parameters are as follows:
[0093] Peripheral edge is equal helix angle edge line, helix angle β=39°, circumferential tooth taper angle κ=4°; end tooth inclination angle η=3°, tooth eccentricity h=1, tooth over-center amount l=2.
[0094] The formed end tooth straight edge and annular edge are as attached Figure 4 Shown. As attached Figure 4 As shown in a, the straight edge of the end tooth has an inclination angle, Figure 4 b represents the off-center amount and over-center amount of the straight edge, Figure 4 The annular edge of the end tooth shown in c is smoothly connected with the straight edge of the end tooth and the edge line of the peripheral tooth.
