<p>As the blanking process of parts mechanical processing, sawing is widely used in advanced manufacturing fields such as automobile industry, aerospace, and engineering machinery. Band sawing has shown significant advantages in large-size workpiece processing, sawing efficiency, and material utilization. However, due to the long-term positioning of band sawing as a rough machining process, its technology is relatively lagging behind, and there are gaps in theoretical mechanism research and process optimization. In recent years, with the continuous emergence of new valuable materials and the increasing demand for lean production, the demand for optimization of band sawing process is becoming more and more urgent. Therefore, this paper first examines the impact of band saw blade structural characteristics on sawing quality, and introduces current optimization methods including heat treatment, surface treatment, band saw blade manufacturing techniques, and sawtooth parameter adjustments. Secondly, it discusses the influence of sawing parameters on sawing quality and elaborates on the optimization methods for sawing parameters containing mechanical model, Taguchi method, and intelligent algorithms. Subsequently, it analyzes the effect of band saw blade vibration on sawing quality and explains vibration detection and suppression methods. Finally, the future development direction of band sawing optimization technology is prospected.</p>
