Abstract
Circular saw blades are fundamental and necessary cutting tools used for sawing, slicing, and related machining processes. In this paper, an innovative and economical design of a circular saw blade with self-clamped cutting inserts used for general purpose steel cutting is presented. The designed circular saw blade consists of a plurality of cutting inserts assembled to a circular saw plate through an elastic deformation-based self-clamping mechanism. Prototypes of the designed circular saw blade were actually fabricated. Slicing tests of workpieces made of JIS S45C carbon steel and JIS SCM440 alloy steel were conducted, and the induced cutting forces and surface roughness were also measured and then evaluated through established response surface models. The resultant cutting forces obtained from all slicing tests were less than 560 N, which indicates that a moderate level of cutting forces would be induced. The values of arithmetical mean roughness obtained from all slicing tests significantly ranged from 1 to 4 μm, which indicates that well surface quality of the machined surface could be achieved. Therefore, the presented circular saw blade was feasible for applications of general purpose steel cutting.
