Abstract
In this paper, a new cutting tool named “driha” is introduced. The tool can perform smoothly both drilling and cutting out of architectural sheet materials, especially board materials such as plywood and aluminum board by hand work. In order to clarify the cutting mechanism of the tool, thecutting resistance variation of driha is measured accurately and compared with the groove cutting process by endmill. The results obtained are as follows: (1) Cutting resistance variation of driha is quite different from that of endmill. (2) The cutting resistance characteristics of driha depend strongly on the length of cylindrical land.
