Abstract: Considering the complexity and instability of the automatic cutting process of single wood boards, this paper, based on the finite element analysis theory, aims to explore the stress and strain laws of single wood boards under different environmental loads, and then design the force analysis scheme for their cutting environment. The research adopts the finite element analysis simulation method. Firstly, the environmental load design process is given, and then based on the finite element analysis method of single wood board cutting, the mechanical properties and variation trends of single wood boards under different materials, thicknesses, moments and support points are analyzed, and the optimal moment solutions corresponding to different thicknesses and rotary cutting radii are solved. The simulation results show that the maximum stress and strain of the wood board are inversely proportional to the thickness and directly proportional to the moment and the long side support can reduce the maximum stress and strain. The research results not only theoretically improve the theory of automatic cutting of single wood boards, but also have significant practical significance for the design of automatic cutting systems.
