[0016] Specific implementation plan
[0017] The specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 1 is a schematic diagram of the method of spiral machining trajectory. As shown in the figure, the discrete surface first establishes the corresponding relationship with the parameter circle based on the mapping, and then generates the processing trajectory of the free-form surface through the plane spiral guidance. Specific steps are as follows:
[0018] 1. First, plan the processing trajectory according to the three-dimensional drawing of the workpiece:
[0019] a. This embodiment uses a solid three-dimensional model. First, the machined surface is meshed with the help of Solidworks software, and the side length of the triangular mesh is 3-5mm, as shown in Figure 2.
[0020] b. Map the meshed processed surface to the circular domain of any given plane, and the mapping technology used is linear parameterizatio...
