Embodiment
[0037] Embodiment: The denture processing tool path generation method of the present invention is mainly completed by two steps of rough machining and finishing, and the generation of the rough machining tool track is divided into two steps of Z direction rough machining trajectory generation and -Z direction rough machining trajectory generation , The generation of the finishing tool path is divided into two steps: Z-direction finishing trajectory generation and -Z-direction finishing trajectory generation.
[0038] The method steps of specific rough machining trajectory generation, such as figure 1 As shown in (a):
[0039] 1. Determine the rough machining material removal area:
[0040] The Z-direction and -Z-direction material removal area is determined by the following formula: first use figure 2 (a) Denture 2D bounding box (Z-axis infinite length) and figure 2 The rough embryo Γ shown in (b) is obtained by Boolean intersection operation figure 2 3D limited box B s...

The invention relates to an artificial-teeth processing route generating method, which belongs to the numeric-control processing technical field, and comprises the following steps that: a cutter track for roughly processing artificial teeth is firstly generated, then a cutter track for precisely processing the artificial teeth is generated, the rough processing of the cutter track is divided into two steps: generation of a Z-direction rough processing route and generation of a negative Z-direction rough processing route, and the precise processing of the cutter track is divided into two steps: generation of Z-direction precise processing route and generation of a negative Z-direction precise processing route. The generation of the rough processing route comprises the following steps that: (1) determining a material removal area; (2) acquiring an intersection outline curve set; (3) processing the intersection outline curve set; (4) generating a processing area; (5) filling routes; and (6) joining the routes. The generation of the precise processing route comprises the following steps that: (1) determining a material removal area; (2) acquiring an intersection outline curve set; (3) processing the intersection outline curve set; (4) generating a processing area; (5) filling routes; and (6) joining the routes. Due to the adoption of the artificial-teeth processing route generating method, the route planning problem of an artificial-teeth numeric-control processing cutter can be effectively solved, and the efficiency problem and the quality stability problem for manually preparing artificial teeth can be solved.
Description
technical field [0001] The invention belongs to the technical field of numerical control processing, and in particular relates to a method for generating a denture processing trajectory Background technique [0002] The preparation of the dental model generally adopts the inverted model method. After the plaster negative model of the tooth root is obtained, the model of the teeth and jaw has been obtained. A positive mold can be produced from the plaster cast, which reflects the patient's oral cavity. After obtaining the positive model, the digital model of the dentures and jaw is described with a grid or spline surface using a point cloud or image-based reconstruction method. On the basis of referring to the anastomotic relationship between the upper and lower jaws and the information of the adjacent teeth, the digital model of the dentures suitable for processing is designed through CAD partial modification. [0003] The invention patent with the patent number of 0081658...
