摘要: The problems of severe sawtooth wear, harsh sawing noise, and low surface quality during the processing of circular saw blades need to be solved. To improve the cutting performance of TiC-based cermet saw blades, microtextures parallel to the cutting edge were fabricated on rough and fine sawteeth by laser machining. The cutting tests were performed on a sawing platform under lubricated conditions. Models of the sawing arc length and working sawtooth cutting force variations were developed for sawing steel pipes, and the accuracy of the sawing force model was verified experimentally. The results indicate that the variations in the sawing force are proportional to the sawing arc length. The circular saw blades with microtextures that did not penetrate the sawtooth rake face exhibited the lowest cutting force, sawing noise, and highest machined surface quality. Furthermore, the worn-out distance of the rougher and finisher sawteeth was reduced by approximately 7.4 % and 44.1 %, respectively, compared with conventional circular saw blades. The main failure modes of sawteeth were tip wear, rake face adhesion, and oxidative wear. In addition, the mechanism by which the textures improve the cutting and wear properties of TiC-based circular saw blades was discussed. This study provided a significant concept for enhancing the cutting performance of circular saw blades and improving the machined surface quality.
