Abstract: To address the high consumption of wear parts in the SQ352 tobacco cutter — a problem caused by a parameter mismatch among grinding wheel feed, blade feed, and cutter head rotation speed due to the limited adjustment angle of the grinding wheel dresser — an innovative cutting-grinding matching system was developed. This system automatically adjusts these key parameters in response to the changing radius of the grinding wheel, thereby enhancing the good cut rate and stability of the shredded tobacco. Based on the mechanical structure of the SQ352 cutter, a micro-adjustment device was integrated into the grinding wheel dresser to expand its operational angle. Field experiments confirmed that as the grinding wheel radius decreases, a corresponding adjustment of the grinding wheel feed, blade feed, and cutter head rotation speed is required. The control system was implemented using Siemens Step-7 software to model these parameters, defining their data types and memory allocation. The Human-Machine Interface (HMI) was developed with Visu+ software, including screen editing and network configuration for the modeled data. Finally, the cutting-grinding matching logic was programmed in Siemens Step-7 to achieve the automated function. The system established in this study significantly reduces the consumption of the tobacco cutter's wear parts while ensuring the stability of the cutting process.
