Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0029] Such as Figure 1-5 shown.

[0030] A feature-based automatic grouping processing method for groove features of plate parts, the flow chart of which is shown in figure 1 As shown, the specific steps are as follows:

[0031] Step 1: Read the part CAM model. In the CAM environment, import the three-dimensional solid model of the part, and at the same time import the tool library information provided by the user and the NC process regulations.

[0032] Step 2: Read part features and create a list of part feature recognition results. The feature recognition result list is the result of feature recognition, which records the feature information contained in the part, including the groove feature, hole feature, rib feature, corner feature, etc. of the part. Plate parts are mainly groove and hole features. A groove feature consists of a horizontal web fa...

Abstract

The invention provides a feature-based automatic groove feature grouping machining method for plate parts. The machining method is characterized in that a feature identification result information list of a part model is extracted, geometrical information of machining regions corresponding to groove features is extracted, the maximum machining cutter diameters of the machining regions are calculated, the maximum machining cutter diameters of the machining regions are contrasted with a cutter table and a numerical control process specification to realize grouping of all the groove feature machining regions, and each group of groove feature machining regions is provided with an optimal cutter. The machining method can automatically conduct cutter selection for technologists, and reduces repeated manual work compared with the mode of manually selecting cutters according to experience; meanwhile, machining operations using the cutter of the same size can be combined due to automatic grouping machining, time is saved for the technologists, and machining efficiency is improved for enterprises.

Description

technical field [0001] The invention relates to a numerical control processing technology for plate parts, in particular to a method for processing groove features of plate parts, in particular to a feature-based automatic grouping method for groove features of plate parts. Background technique [0002] At present, CAM technology has been widely used in the field of aerospace manufacturing. Using CAM software for programming can improve the programming efficiency of craftsmen to a certain extent, improve processing efficiency, shorten the manufacturing cycle of products, and save production costs. [0003] Plate parts are mostly used in aircraft structural parts and aerospace structural parts. They are characterized by multi-groove and hole features. When compiling such parts, craftsmen often need to compile dozens of processing operations and manually select many driving geometries. Setting up suitable tools and a large number of processing parameters, the workload of progr...
