Research of improving the woodworking western push saw by special teeth design
|關鍵字:||齒尖高低差;未來目;tooth tip height;Mirai-Me|
Woodworking handsaws can be divided into two types: Japanese pull saw and western push saw. In general, the evaluation of Japanese saw is higher because of the special designs of teeth and heat treatment, which can reduce the force required in cutting. On the other hand, the western saw is more suitable for working with workbenches or other woodworker's equipments than the Japanese saw, and therefore it has a large market share. This project intends to improves the overall performance of the western push saw and increase its added value by the following steps. Add 〖Mirai-Me〗^TM and tooth tip height to the western saw to improve its cutting efficiency. The western push saw, which will be improved in this project, is produced by TRT. It will design the experimental equipment. The performance differences between new product and original product are decided by cutting efficiency test and sawing test by human, that are also carried out to understand the correlation between the 〖Mirai-Me〗^TM and the tooth tip height. From the experiment results, 〖Mirai-Me〗^TM and tooth tip height can add in the western push saw to improve its cutting efficiency, reducing 25% cutting force. In addition, Experiments show that the same results of sawing test to human and Experimental equipment.
