Background In building construction, in order to meet the decoration style, the non-bearing wall cutting arched door openings, round window openings and arc wall surfaces are increasingly widely applied in recent years, and extremely high requirements are placed on the precision, texture and attractiveness of the construction process. Currently, for the construction of such circular arc vaults, there are mainly three traditional ways: the manual handheld cutting machine works, namely an operator holds the cutting machine to cut along a circular arc line drawn in advance, and the absolute smoothness of a cutting track is extremely difficult to keep due to the limitation of the movement of the arm of the human body, so that the cutting surface is often waved to undulate or deviate from a preset circular arc. The sectional cutting splicing method is to decompose the arc into a plurality of short straight line segments for cutting for a plurality of times, and then manually polish and trim the arc in the later period, so that obvious stubble connecting marks or rugged are often left on the cut wall surface, and the smooth feeling of the vault lines is seriously damaged. The wood board splicing molding method is a common alternative scheme at present, constructors firstly use wood materials such as multi-layer boards, density boards and the like, cut the wood materials into strips or blocks according to a designed radian, splice the wood board into an arched outline in a gluing mode, a nailing mode and the like, the wood board is formed by splicing a plurality of pieces, a large number of glue joints and nail holes exist, the wood is easily subjected to thermal expansion and shrinkage or moisture absorption deformation under the influence of environmental temperature and humidity changes, and a putty layer at a spliced part is easily cracked, peeled off or even falls off, so that the decorative effect and durability are seriously influenced.
