Theory Study of Leather Cutting Force and Adsorption Force

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.
