Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing.
[0030] Such as figure 1 Shown, the present invention comprises the following steps:
[0031] (1) Create an inspection knowledge base associated with detection features, where detection features are defined as detection elements related to detection information, detection information includes roughness, shape tolerance, position tolerance, and size tolerance; detection elements include inner holes, cylinders, Flat surfaces, curved surfaces, convex grooves, grooves, etc. The detection feature can be expressed as IF=(IM,IE), where IF represents the detection feature, IM represents the detection information, and IE represents the detection element.
[0032] The process of establishing the inspection knowledge base is as follows:
[0033] (11) Divide the inspection knowledge base, and divide the inspection knowledge base into fuselage, cylinder head, connecting rod, crankshaf...

The invention discloses an inspection rule automatic generation method based on detection characteristics, and the method comprises the following steps: inputting a three-dimensional process model, obtaining the detection characteristics, and obtaining detection elements and detection information; Retrieving an inspection knowledge base based on the detection information of the detection characteristics, further searching the inspection knowledge base based on the detection meta-information of the detection characteristics, generating an inspection model if the detection knowledge base is matched with the detection meta-information, and finally obtaining an inspection regulation file; And if not, retrieving the detection resource library according to the determined detection characteristics, adding a detection tool, retrieving the process rule library, adding a detection method, generating an inspection model, and finally obtaining an inspection regulation file. According to the invention, a traditional paper inspection sheet is digitized, and is converted into the regulation file in the uniform format, the special inspection regulation digital representation method for the digitalinspection system is formed, a reliable data source is provided for digital quality inspection technology research, and the problems that existing production site inspection specifications are uneven, nonstandard and incomplete, and management vulnerabilities are caused are solved.
Description
technical field [0001] The invention relates to a product quality detection method, in particular to a method for automatically generating inspection rules based on detection features. Background technique [0002] At present, products have entered the stage of digital manufacturing based on 3D models, realizing paperless design and production, while the traditional inspection mode is to inspect and test products based on 2D engineering drawings and manufacturing outlines, which cannot meet the requirements of full 3D digital manufacturing of products. Therefore, the realization of product digital inspection and the improvement of inspection efficiency and level have become the key links to fully realize the digital manufacturing of products. [0003] On the basis of the universal application of manufacturing technology, inspection procedures are indispensable regulatory documents for inspection operations, which are used to monitor and measure purchased products, in-process...
