Experimental and Numerical Study on Regulation of Cutting Temperature during the Circular Sawing of 45 Steel

Studying the cutting temperature is critical for unlocking secrets of sawblade wear, lifespan, and metallurgical alterations beneath surface. This paper describes an investigation into 45 steel during dry sawing, using a cemented carbide circular saw blade under various conditions. A acquisition system was developed, enabling determination average arc zone in workpiece sawtooth tip via semi-automated thermocouple measurement embedded dynamic artificial method, respectively. Results obtained from these two methods indicate positive correlation between sawing speed feed rate, with optimal combination process parameters identified maintaining stability within reasonable ranges. Finite element simulations reveal cyclical fluctuation along surface sawtooth, gradual decrease after increase intermittent step, confirm relationship rates observed experimentally. Overall, this study presents valuable insights changes occurring process, important implications improving productivity industrial applications.
