Optimal cutting method for wood surface defects

Abstract

The invention discloses an optimal cutting method for wood surface defects, and relates to the technical field of wood processing. The cutting method specifically comprises the following steps that S1, firstly, rubber wood undergoes manual blind cutting from raw material, transverse polishing and vertical polishing, then a wood block with the length of about 300 mm, the width of about 80 mm and the thickness of about 25 mm is cut, the wood usually has the defects such as black knots, white joints, tree centers, missing edges, cracks, inclined heads and damage, the wood is cut according to thedistribution rule of the defects, and the cut wood is divided into four types namely, an AA material, an AB material, a C material and a waste material. According to the optimal cutting method for thewood surface defects, the effects that a deep learning analysis algorithm is adopted to accomplish the defection on the surface detects of the wood, the yield of the wood can reach the maximum economic benefit, the labor cost is greatly saved, the production efficiency is improved, the utilization value of the wood is improved, and the problems that the cutting position is prone to be misjudged manually and the manual line drawing efficiency is low are solved can be achieved.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to an optimal cutting method for wood surface defects. Background technique [0002] Rubber wood is cut manually from raw materials, polished horizontally and vertically, and then cut out a piece of wood about 300mm long, 80mm wide, and 25mm thick. These woods usually have black knots, white knots, tree cores, missing edges, and cracks. , slanted head, damage and other defects, the existence of these defects will affect the appearance of furniture made of wood, so it is necessary to cut the wood according to the distribution of the defects. After cutting, the wood is divided into four types: AA material, AB material, C material ,scrap. Among them, the wood length of AA material, AB material and C material is all greater than 100mm, and the length of waste material is less than 100mm. AA material means that there are no defects on both sides, AB material means that only one ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an optimal cutting method for wood surface defects, which solves the problem that human beings may misjudge the cutting position in order to pursue production speed, fail to reach the optimal cutting plan, and reduce the cost of wood. The high material yield will consume a lot of time, affect the output efficiency of wood, damage the health of the staff, and the problem of high labor costs
