Abstract： Cutting and de-bagging is a chaff-bag separation technique that prevents plastic residue from wasted mushroom inoculation bags. In order to explore the cutting parameter，this study designed an experimental platform and conducted tests on oyster mushroom substrate bags. Single-factor experiments were performed to investigate the effects of cutting speed， slip-cutting angle，and cutting depth on the peak cutting resistance and incision quality. A Box-Behnken multi-factor experimental design was employed，with cutting speed， slip-cuting angle，and cutting depth as independent variables，and peak cuting resistance as the evaluation index，leading to the establishment of a regression model. The multivariate experimental results indicated that the peak cutting resistance decreased with increasing cuting speed and slip-cutting angle，while it increased exponentially with cutting depth. A significant interaction was observed between the slip-cutting angle and cuting depth. Optimization via response surface methodology identified an optimal parameter combination，with a cutting speed of 0.56m/s ，a cutting depth of 10mm ，and a slip-cutting angle of 32.8∘ ，resulting in a predicted peak cutting resistance of 13.6N . Experimental validation confirmed an error margin below 5% . Based on these optimized parameters，a prototype bag-sliting device was developed and tested. Under an initial cuting depth of 10mm ， the prototype achieved a bag-breaking success rate exceeding 95% . The results have provided both parametric foundations and structural references for the development of the waste mushroom substrate bag separation apparatus.
