- Group A includes a total of seven teeth, two straight teeth and five set teeth.
- Large set teeth, small set teeth, small set teeth, small set teeth, small set teeth (large 4: small 1) 2.
- the large set teeth form a cut surface, and the larger the number, the cleaner the cut surface.
- the number of large set teeth increases, the number of small set teeth decreases, and the cutting load of the small set teeth increases, reducing the life of the saw blade. Therefore, a combination that makes the tooth cutting load as uniform as possible is good.
- the straight teeth have a large proportion of overlapping small cutting teeth and cutting grooves [kerf], and it is considered that similar cutting loads are generated on the straight teeth and the small setting teeth.
- the balance of the cutting load is best because the two straight teeth reduce the load on the small set teeth. Accordingly, the number of set teeth is determined as a combination of three large set teeth and two small set teeth.
- sequence (permutation) containing 2 right large set teeth Rw 2.
- Table 6-1 shows the arrangement (permutation) of good clams extracted from “Table 1” to “Table 5”.

- the wear amount is divided into a large set tooth and a small set tooth among the 14 teeth of Group A (7 teeth) and Group B (7 teeth), and the maximum load, respectively. Then, the amount of wear of the tooth with the minimum load was measured. In addition, the average value of the tooth
- Table 7 shows the teeth used for calculating the average value for each of the saw blades (No. 1 to No. 10) used in the experiment.
- FIG. 2 is a graph showing the measurement results of cutting noise. From this graph, no. It can be seen that the cutting noises of 2, 4, 6, and 8 are significantly lower than those of the others.
- FIG. 3 is a graph showing the measurement results of the tip wear amount (average value of the left and right set teeth) of the small set teeth. From this graph, no. It can be seen that the wear amount difference between 1, 2, 4, 6, and 8 (the difference between the wear amount of the maximum load tooth and the wear amount of the minimum load tooth) is small, and the wear amount is uniform compared to the other.
- FIG. 4 is a graph showing the measurement results of the tip wear amount (average value of the left and right set teeth) of the large set teeth. From this graph, no. It can be seen that the difference in wear amount between 2, 4, 5, 6, 7, 8, and 9 is small, and the wear amount is more uniform than the others.
- inter-tooth pitch number “6” represents the cutting load generated in Rw2
- the pitch number “2” represents the cutting load generated in Rw3. The larger the number, the larger the load.
- Table 6-2 describes both the number of pitches of the left set teeth and the number of pitches of the right set teeth [R-side set teeth]. The maximum and minimum pitch numbers (cutting load) are described. The ratio to the value is the same for both left and right set teeth. Therefore, the ratio may be calculated by either one. Here, the ratio is calculated using the right set teeth as an example.
- No. 1 includes three right large set teeth (Rw) of (Rw1 ⁇ ) Rw2, (Rw2 ⁇ ) Rw3, and (Rw3 ⁇ ) Rw1.
- each cutting amount of Rw1 and Rw2 is approximately three times the cutting amount of Rw3, and each cutting load of Rw1 and Rw2 is approximately three times the cutting load of Rw3.
