A study on finished dimensions of band saw blade

Abstract

Among the dimensions of finished band saw blabe, height of tooth H, size of set b and pitch t were measured about all teeth (200_??_500) on one blade, and the precision of finishing was investigated.
The results are indicated on Table 1, and as follows:
1) The irregularity of height of tooth H is specially large in comparison with the one of other dimensions.
2) As the standard of decision about the irregularity of H, the theoretical cutting depth δ₀ is to be taken.
3) The irregularity of pitch t is neglisible.
4) Cutting area of a tooth may be five or six times greater than the theoretical on. Thus co large safty factor is to be considered in respect to discharge of saw dust and strength of tooth.
5) Or, woods are not able to be sawn at the decided speed, and so the efficiency comes down.
6) The irregularity of b and H influence upon the evenness of sawn woods and deteriorate the quality of woods.
