摘要： Long-term tracking tests revealed that the adaptive spiral profiling automatic rubber cutter is prone to "knife off" and "knife jumping" states during the cutting process. These issues result in inconsistent skin thickness and poor cutting surface uniformity and can even damage natural rubber trees, leading to reduced yield, disease, and potentially death. This paper presents experimental research on the parameters affecting the performance of the adaptive spiral profiling automatic rubber cutter. It explores the impact of key parameters on cutter performance and establishes a mathematical model relating these parameters to the peel thickness and cutting surface uniformity rates. Through multi-objective parameter optimization, the optimal parameter combination was determined: a cutting speed of 15 s/knife, a blade thickness of 0.50 mm, and a bending angle of 27.5 degrees. In six tests, the average peel thickness and cutting surface uniformity rates were 97.5% and 96.5%, respectively. These results meet national standards, suggesting that the optimized parameters significantly improve the rubber cutter's performance. The results meet national standards, demonstrating that the optimized parameters improve the peel thickness and cutting surface uniformity. The regression model is reliable and provides a foundation for selecting better parameter combinations for future prototypes.
