This study identifies the relationship between the rotational speed variations of a newly profiled saw and saw cylinder with the machine’s performance, seed damage, and fiber quality (impurity accumulation). The research was conducted on a DP-30 laboratory stand using cotton samples of the "Yoleta" and "R3" varieties. The input parameters considered were the saw tooth height, pitch, and rotational speed. Output parameters included fiber productivity, seed damage, and fiber impurity indicators. The study found that productivity increased with greater tooth size and rotational speed, while seed damage remained relatively stable.
