Problems solved by technology

[0004] Designers use 3D modeling technology to model the blades and then use the process planning of the craftsmen to prepare the blade path. On the one hand, it has a large amount of repetitive labor and low efficiency; on the other hand, the blade structure is special and the process parameters are not easy. As a result, the quality of the processing program is uneven. At the same time, the length of the blade is relatively large, and the thickness of the blade body is small, which is prone to torsional deformation during processing.

Embodiment 1

[0046] see Figure 1-Figure 3 , the intelligent manufacturing method of the fan blade is characterized in that by defining the processing knowledge base and the processing resource base in the computer-aided processing tool, the feature recognition rules and feature processing rules are compiled for the blade model created by applying MBD technology, and the process is completed through the program Identify the characteristics of the blade and intelligently create the blade processing technology, and then send the program to the vertical four-axis milling machine equipped with dual heads and sensors for processing. In this way, the quality of the processed blade is guaranteed on the one hand, and the On the one hand, the automatic feedback of processing information and the automatic execution of related commands are realized, so as to realize the intelligentization of blade processing program and the intelligentization of blade processing and manufacturing. The operation steps...

Embodiment 2

[0047] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0048] (1) Define the types of processing operations that may be used in the blade processing process in the form of files in a specific location as a processing operation template set. When realizing the intelligent manufacturing method of the blade, the extension definition is carried out in the existing computer-aided processing tools. In general computer-aided processing tools, if a part needs to be programmed with NC toolpath, a series of steps such as creating machine tool coordinate system, creating geometry, creating tool, and creating processing operation are required, and the steps are relatively cumbersome.

[0049] (2) Define the tool types and machine tool types that may be used in blade processing in the form of files in a specific location as a processing resource library. In the process of creating tool paths for various parts, it is generally...

Embodiment 3

[0058] Embodiment three: This implementation is described as follows according to the figure:

[0059] first in figure 1 The system architecture of this method is described in , this method uses the existing CAM tool as the platform, after opening the blade model to be processed in the CAM tool, by specifying the blade as the processing object, firstly call the processing knowledge base through the custom menu to process the blade Feature Lookup, checks for features contained in the library. By comparing the existing features in the processing knowledge base with the target object, the identified features are fed back to the CAM tool, and the identified features are listed in the form of a list in the CAM tool.

[0060]After the identification of the blade features is completed, select the identified blade features, and create a machining operation for the identified blade features by selecting a custom menu command. At this time, it is a call to the machining rules in the ma...

Abstract

The invention discloses an intelligent fan blade manufacturing method. The method includes the specific steps of setting up a machining operation template set, setting up a machining resource database, setting up a machining knowledge database, developing a new menu command in a CAM tool, appointing a blade set up through the MBD technology in the CAM tool as a tool body, searching for the blade characteristics, setting up a machining operation method for the found characteristics, automatically generating a tool path, conducting post-processing on the generated tool path program, and sending the program to a four-shaft vertical milling machine to conduct blade milling. When the method is applied, work efficiency of programming personnel is improved in the programming process in the future, repeated operation of the mature process is avoided, an enterprise can conveniently store the mature process, and meanwhile the blade machining quality is effectively ensured.

Description

technical field [0001] The invention relates to the field of computer-aided manufacturing, specifically, how to quickly complete the creation of blade machining tool tracks, tool selection and real-time monitoring of the blade machining process. Background technique [0002] With the rapid development of my country's aviation industry, its research and development, manufacturing and other various modes have also undergone major changes. Initially, the "drawing board" project was carried out in the aviation industry, and all drawings were replaced by computer graphics, gradually avoiding manual work. Drawing is labor-intensive and the workload is cumbersome. With the development of 3D technology, 3D drawing is gradually applied to the design field of aviation industry. The application of 3D technology realizes the spatial visualization of parts, which facilitates the staff's conception of the part structure. Today, my country is gradually developing a R&D and production mode...
