Point distribution method and system for complex special-shaped holes

Abstract

The invention relates to a point distribution method and system for complex special-shaped holes. The method comprises the following steps: classifying an upper end surface topological line and a lower end surface topological line to obtain an upper end line and a lower end line; obtaining geometric average points of the upper end line and the lower end line; determining a positioning point of thespecial-shaped hole according to the geometric average point; determining an upper point distribution layer and a lower point distribution layer according to the positioning points, wherein the distance between the positioning point and the upper point distribution layer is recorded as a first distance, and the distance between the positioning point and the lower point distribution layer is recorded as a second distance; obtaining the radius and the height of the special-shaped hole; determining the type of the special-shaped hole according to the radius and height of the special-shaped hole;acquiring the number of point distribution layers and the number of points to be distributed; calculating interlayer spacing and measuring point spacing according to the type of the special-shaped hole, the first distance, the second distance, the number of point distribution layers and the number of to-be-distributed points; and determining measuring point coordinates and a measuring point direction according to the measuring point spacing and the interlayer spacing. According to the invention, automatic point distribution of various types of special-shaped holes can be realized, and the measuring point planning efficiency and the automation degree are improved.

Description

technical field [0001] The invention relates to the field of point distribution of special-shaped holes, in particular to a method and system for point distribution of complex special-shaped holes. Background technique [0002] At present, the measurement point planning module of the common computer-aided inspection planning (Computer Aided Inspection Planning, CAIP) system can realize the automatic distribution of points for straight holes, but the ability of automatic distribution of irregular holes such as curved holes and oblique holes on the end surface is still insufficient. , Many situations require manual settings, so the existing planning of measuring points for special-shaped holes is low in efficiency and low in automation. Contents of the invention [0003] The object of the present invention is to provide a method and system for distributing points of complex special-shaped holes, realize automatic point distribution of various types of special-shaped holes, a...
