Embodiment Construction

[0036] The following is a specific example of the present invention, showing the automatic generation of intelligent reasoning types of measurement strategies. However, the present invention is not limited to these examples.

[0037] Step 1: Establish a 3D model of the part in the software UG10.0 based on MBD technology, and construct the ontology model of the part's geometric information and non-geometric information, such as image 3 shown;

[0038] According to the body model of the 3D model of the part, it includes: line individuals: CAxis_2-1 and CPlanar_3; surface individuals: Cylindrical_5-1, Planae_6-1; label individuals: FLTolerance_2-1, Dimension_1-1, Datum_3-1.

[0039] Assertion formula set A A . According to the affiliation relationship between the feature and the label, and the object attributes in Table 2, the assertion formula set of the affiliation relationship between the feature and the label is obtained A A ;

[0040] A A={Cylindrical_5(Cylindrical...

Abstract

The invention belongs to the field of product precision measurement and computer application, and relates to an intelligent reasoning method for a geometric error measurement strategy of an intelligent three-coordinate measuring machine (CMM), which can be used for carrying out part error measurement in CMM equipment and providing guidance for intelligent measurement. The method is realized by the following steps: step 1, acquiring annotation information in a three-dimensional model, and constructing an ontology model; 2, intelligently reasoning elements needing to be measured; step 3, giving an element measurement strategy; 4, constructing an inference rule of a measurement strategy; and 5, developing an intelligent reasoning program of a measurement strategy by using a Java language, wherein the intelligent reasoning program is used for automatically generating the measurement strategy.

Description

technical field [0001] The invention belongs to the field of product precision measurement and computer application, and relates to an intelligent reasoning method of an intelligent coordinate measuring machine (Coordinate Measuring Machine, CMM) geometric error measurement strategy, which can be used for part error measurement in CMM equipment, and is an intelligent measurement method. Provide guidance. Background technique [0002] During the manufacturing process of parts, there must be manufacturing errors in the size, geometric shape and relative position of geometric elements. Due to the rapid development of computer technology and the demand for artificial intelligence in mechanical design and manufacturing, the research on intelligent inspection of parts manufacturing errors has become a trend. At this stage, the inspection of part errors, the number and layout of sampling points, that is, the measurement strategy are the main factors affecting the efficiency, accur...
