Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0065] Such as Figure 1-10 shown.

[0066] A method for quickly generating machining tracks for web milling of aircraft structural parts, the flow chart of which is shown in figure 1 shown, including the following steps:

[0067] First, in the CAM environment, click the web surface to be processed by the mouse, and use the selected web surface as the seed surface to expand the surface to obtain the feature surface column corresponding to the web surface. Matching and constructing the columns to realize the automatic construction of the web milling processing area, such as figure 2 As shown, the processing parameters are determined through process decision-making; finally, the geometric elements constituting the processing area and the results of process decision-making are automatically assigned to the corresponding processing operations in the CA...

Abstract

A rapid generating method of the milling path of a web of an airplane structural member belongs to the technical field of CAM. The rapid generating method comprises the following steps: at first, clicking a web surface on which a tool path needs to be generated in a part model through a mouse in a CAM system, automatically constructing a milling area of the web of the clicked web surface, then selecting processing technology information of the clicked web surface automatically generated or manually inputted according to data in a process database, and achieving the rapid and automatic generation of the processing area and the processing path. The method is high in computing efficiency and strong in flexibility, reduces the programming workload of engineers, meanwhile, supports the batch processing to a single web surface and a plurality of web surfaces, and can meet different requirements of engineers.

Description

technical field [0001] The invention relates to a numerical control processing method, in particular to a method for automatically generating milling processing tracks, in particular to a rapid generation method for web milling processing tracks of aircraft structural parts. Background technique [0002] As we all know, aircraft structural parts are the main load-bearing components of aircraft, including frames, beams, wall panels and other structural types. Due to the high quality requirements and short processing cycle of aircraft structural parts, CNC machining is mainly performed on high-end CNC machine tools. Through years of technological transformation, my country's aviation manufacturing enterprises have introduced and developed a large number of high-value, high-cost CNC machine tools and supporting equipment, but the overall utilization rate of equipment is less than 40%. One of the main reasons is the low efficiency of CNC programming. For large integral structural...
