By the way, in the conventional roughing end mill, the position of the corrugated cutting edge is sequentially shifted in phase for each blade part (3). The phase amount is "waveform pitch (p) ÷ number of blade parts (3) (N)", and in any axis-perpendicular cross section of the blade part, the radial dimension of each cutting edge is different, and the same-shaped chips There are no blades. This is shown in an axis-perpendicular cross-sectional view taken along the line A-A' in Figure 1.
As shown in FIG. 9, if the number of blade portions (3) is 6, a total of 6 blades will be formed from 1 blade to (1) to &6 blades. The dimensions of the A1 blade (1) are the same as the tool virtual diameter (4), but the dimensions from JFL2 blade (II) to Ni6 blade (VI) are the same as the tool virtual diameter (4).

The hatched part on the drawing indicates the cutting cross-sectional area (PXF) per rotation of the end mill in the axial length corresponding to one pitch (P) of the corrugated cutting edge (5) of the end mill, It shows that cutting is performed using six wave-shaped cutting edges (5). Furthermore, from Fig. 11 to Fig. 15, the radius (R) of the corrugated cutting edge of the conventional roughing end mill is the same, and the waveform pitch (p) and the number of blade parts (N)'! r is a cutting action diagram (envelope) obtained by cutting with end mills having different values (cutting feed amount F is constant).

も軸方向のみを細分割される。As shown in Table 1 (opening force from Figures 11 to 15 above), the roughing end mill improves cutting by increasing the number of teeth (N) in the blade section and reducing the waveform pitch (P). The number of corrugated cutting edges involved can be increased, and the number of cutting edges per cutting edge can be increased. However, as mentioned above, with conventional end mills, the cutting cross section per tooth can only be divided in the axial direction of the end mill. However, it cannot be divided at all in the radial direction. For example, as the number (N) of the cutting edge (3) increases, the cutting cross section (Hl) of the wave-shaped cutting edge (5) in FIG. When the waveform pitch (P) is reduced, the cut section (H2) in Fig. 13 is obtained.Also, the blade section (3)
If the number (N) is increased and the waveform pitch (P) is reduced at the same time, the cut cross section (H4) shown in FIG. 15 is obtained, and both are subdivided only in the axial direction.

分断できないのである。No matter how finely the cutting section is divided only in the axial direction, the specific cutting force only increases, and the cutting feed cannot be increased. For this reason, no particular effect on extending tool life or improving machining efficiency can be expected. In the above conventional products, in the radial direction (cutting feed direction) of the end mill, the cutting feed amount (F) per rotation of the end mill is the number of blades (N), the waveform pitch (Pl), and the waveform cutting edge - blade. Since it is the same as the cutting feed amount per hit, the cutting section cannot be divided in the radial direction.

(Function) The end mill according to the present invention has twice the number of cutting edges of the waveform involved in cutting per revolution compared to conventional products, and the number of cutting edges of the waveform per revolution is twice as large as that of the conventional product. The cutting load on the cutting edge will be reduced to 100%, allowing for light cutting. In addition, even if the cutting feed amount is doubled from the above case, the cutting amount of the corrugated cutting edge is not different from that of the conventional product.

Fig. 3 is a cross-sectional view taken at right angles to the axis from the line A-A" in Fig. 1, and shows a six-blade roughing end mill. The pitch (P) of the corrugated cutting edge is half that of the conventional product, that is, P'2F/2, where P is the pitch of the corrugated cutting edge and S=2. This is an enlarged view of the rake face side force/radial cutting edge (5) indicated by the arrow.The position of the wave-shaped cutting edge (5) of each cutting edge (3) is -moon of the cutting edge (5). The phase is shifted sequentially by pitch (p) Although the section is perpendicular to the axis, the radial dimension of each cutting blade on the D-D line is the virtual outer diameter, W (L

た。(Effects) As described above, the cutting edges are arranged so that two or more cutting edges having the same dimensions and the same shape appear on the exclusive plane perpendicular to the axis at any position of the blade portion. As a result, the cutting cross-sectional area is divided not only in the axial direction but also in the radial direction, and the depth of cut per corrugated cutting edge is half that of conventional products.
This reduces the amount of wear on the cutting edge and significantly improves the life of the cutting edge. In addition, even if the cutting feed rate is twice that of a conventional roughing end mill, the cutting load per corrugated blade is 17 to 18 when compared with the conventional cutting life test results shown in the same figure (A). It has doubled its lifespan.
