Curved wood component cutting system and method

Abstract

The invention discloses a curved wood component cutting system and method, and aims to solve the problems of serious material waste, low processing efficiency and limited processing range in the priorart. The cutting system comprises a computer, a control system, a cutting device and a driving mechanism used for driving the cutting device; the computer comprises a modeling unit, a shape finding unit, a path planning unit and a programming unit; through the modeling unit and the shape finding unit of the computer, the minimum-volume initial component material wrapping a target curve componentis directly found, a cutting program is output through the path planning unit and the programming unit, the cutting device is controlled to conduct cutting according to a cutting path, so that material waste is avoided, and the cutting accuracy and the cutting efficiency are improved; the cutting device is driven by the driving mechanism to move, so that the spatial motion freedom degree is improved, accordingly, more complex components can be machined, the machining range is enlarged, and the cutting device is suitable for rapid cutting forming of single-curve and double-curve components.

Description

Technical field[0001]The invention relates to a system and method for cutting curved wooden components, belonging to the technical field of architectural wooden structures.Background technique[0002]The glulam components in the building can be divided into four types: linear components (the center curve of the component is a single curve, and the cross section is a uniform rectangle without torsion), and the single curve component (the center curve of the component is a single curve, and the cross section is a uniform rectangle without torsion. ), hyperbolic members without torsion (the center curve of the member is a spatial hyperbola, and the cross section is a uniform quadrilateral without torsion), and curved members with torsion (the center curve of the member is a plane curve or a space hyperbola, and the section is a torsion change Quadrilateral). Among them, linear components and single-curved components can be directly produced by a splicing machine, but the special-shaped h...

Problems solved by technology

Five-axis CNC milling needs to use milling tools to remove excess material layer by layer, and the processing efficiency decreases with the increase of the cutting volume. At the same time, a large amount of wood chips will be generated during the milling process, and the material waste is serious

Some band sawing machines are capable of machining single-curved components by rotating the band saw along one axis, but still cannot process hyperbolic components

[0005] Therefore, whether it is from the perspective of processing quality, material efficiency or processing range, the current processing technology of glued wood components cannot meet the needs of buildings for complex hyperbolic components, which is a major obstacle restricting the development of wood structure buildings.
