摘要

通过采集实木异形零部件的尺寸、结构、工艺和应用场景等属性指标，对实木异形零部件进行横切处理，确定其横断面特征。基于横断面沿纵向延伸生成曲面的路径，将曲面划分为挤出形曲面与扫掠形曲面，并实现零部件曲面与对应类别的精准匹配，得到挤出形零部件和扫掠形零部件。根据横断面沿中轴线旋转生成曲面的路径，将曲面划分为回转形曲面与螺旋形曲面，完成零部件曲面与对应类别的匹配，形成回转形零部件和螺旋形零部件。若零部件横断面与纵向延展方向均为复杂曲线，则其归类为自由形曲面，并匹配对应零部件曲面，最终形成自由形零部件；同时对不同类别零部件的曲面进行数学描述，以满足实际生产需求。在此基础上，简要阐述分类后零部件的加工工艺和适用设备，明确加工流程，确保分类结果可指导生产实践，为定制化实木家具企业的生产优化与效率提升提供理论依据和实践参考。

Abstract

The specially shaped solid wood components are subjected to cross-sectional processing for determining their cross-sectional characteristics. Based on the path of generating surfaces along the longitudinal extension of the cross-section

the surfaces can be divided into extruded surfaces and swept surfaces

which assist to achieve and precise matching of part surfaces with corresponding categories. Furthermore

based on the path of the cross-section rotating along the central axis to generate the surface

the surface can be divided into a rotating surface and a spiral surface

completing the matching of the part surface with the corresponding category

forming a rotating part and a spiral component. If both cross-section and longitudinal extension direction of a component are complex curves

it can be classified as a free-form surface matching the corresponding part surface

ultimately forming a free-form component. Simultaneously

the surfaces of different categories of components can be mathematically described to meet actual production needs. On this basis

this study examined the attribute indicators

including size

structure

process

and application scenarios

of existing specially shaped solid wood components

briefly explained the processing technology and applicable equipment of the classified components

and clarified the processing flow

which ensured that the precise classification results could guide production practice and provided theoretical basis and practical reference for the production optimization and efficiency improvement of customized solid wood furniture enterprises.
