摘　　要：在先进皮革数控裁床裁剪加工过程中,需要根据所裁剪皮革的吸附力需求确定吸附强度,因此有必要探讨影响真空吸附力的因素。皮革切割力是决定吸附力的重要因素。分析影响皮革切割力的因素,建立皮革切割力的数学模型,并提出要使裁刀锋利主要方法是减小切割角。利用理论力学相关理论,通过皮革力矩平衡建立皮革吸附力的数学模型。该模型的建立,为以后的裁床设计提供了理论依据。In machining process of advanced leather cutting machine, absorbent strength should be determined according to adsorption requirement of leather, so it is necessary to explore factors influencing vacuum absorption force. Leather cutting force is the important factor on adsorption force. The factors affecting leather cutting force were analyzed. The mathematical model of the leather cutting force was established. It was proposed the main method to make blade sharp was to reduce the blade cutting angle. By using theoretical mechanics theory, through moment balance, the mathematical model of the leather absorption force was established. It provides theory foundation for design of different cutting machines.
