针对传统的门锁孔槽加工方法存在的问题,提出具有互相性生产与安装的高质量木门要采用数控加工方法。以数学方法,建立了门锁孔槽数控加工三维曲面立体模型与数学解析模型,是将包络加工法与门锁孔槽加工工艺结合起来,使传统的工艺方法数学化。通过门锁孔槽数学描述为门锁孔槽数控加工参数的合理选择以及视频再现提供理论基础。利用门锁孔槽数控加工三维曲面的数学模型F(X,Y,Z),建立面向车间(WOP)的门锁孔槽数控加工模式,可在一台机床上加工出能够保证互换性生产与安装的各种门锁孔槽。
Aiming at the existing problems in the processing methods of the traditional door lock slot, it is proposed that the high-quality wooden door with the mutual production and installation should adopt the numerical control processing method. With mathematic method, the three-dimensional curved surface model and mathematical analytical model of NC machining of door lock slot are established, which is a combination of the envelope processing method and the door lock slot machining process to make the traditional process method mathematic. Through the mathematical description of the keyhole slot, it provides a theoretical basis for the reasonable choice of numerical control processing parameters of the keyhole slot and video reproduction. The mathematical model F (X, Y, Z) of three-dimensional curved surface machining is established by using the keyhole slot of NC, and the keyhole slot NC machining mode oriented to the workshop (WOP) is established to ensure the interchangeable production With a variety of door locks installed slot.
