Abstract

The invention patent provides an intelligent planning method for a three-coordinate detection point of a complex curved surface component. Existing detection experiences are summarized, various typesof detection point planning methods are established, and the methods comprise a method of planning a detection point along a curved surface edge, a method of planning a detection point along a curvedsurface center line, a step of uniformly planning a detection point in a curved surface. The shape of the curved surface to be detected is divided into an annular surface, a round surface, a complex contour surface and a rectangular surface. A matrix algorithm is designed, by identifying the information of type and area of the curved surface, the detection point planning method and the curved surface are intelligently combined, an appropriate detection point planning method is selected for each curved surface, the layout parameters of a detection point are adaptively adjusted, and the detection point is automatically planned at the corresponding position. Compared with the prior art, the detection point planning is changed to the compliance with the standard or the specification from the compliance with an experience traditionally, a manual mode is changed to an automatic mode, the standardization and rationality of the detection point planning are improved, and the automation and intelligence of detection point planning are realized.

Description

technical field [0001] The invention relates to a detection point planning method for coordinate detection, in particular to an intelligent planning method for three-coordinate detection points of complex curved surface parts. Background technique [0002] Intelligent three-coordinate measurement detection planning mainly includes the following four points: (1) selection of probe and probe direction; (2) determination of the number of measurement points on the element to be measured and the distribution of measurement points; (3) selection of the global optimal detection path Planning; (4) Detection path collision check and avoidance. [0003] The determination of the number of measurement points on the element to be measured and the distribution of measurement points are also called the planning of three-coordinate detection points. Three-coordinate measurement, from the perspective of detection efficiency and measurement error, on the one hand, the number of measurement p...
