A Reconstruction Method of Weld Curve in Complex Space Based on Creo and Matlab

Abstract

The invention discloses a reconstruction method of a complex space weld curve based on Creo and Matlab. The basic steps include: (1) copying the curve; (2) generation of starting point and setting of offset; (3) array of discrete points ;(4) Export discrete points as .igs format files; (5) Discrete points import and save as .pts format files; (6) Discrete point conversion; (7) Curve reconstruction. Advantages: It is easy to use Creo software to discretize complex weld curves, and the exported discrete point coordinates can be easily applied to Matlab for reconstruction, thereby improving work efficiency.

Description

technical field [0001] The invention relates to a reconstruction method of a complex space weld curve based on Creo and Matlab, and belongs to the technical field of computer graphics. Background technique [0002] In industrial production, various types of curves are often encountered, such as the cross-sectional circular contour curve of the shaft, the helix of the thread, the tooth profile curve of the gear tooth, the intersecting line curve, the sine wave signal curve, etc., and the shape is more complex Curves, such as the curve of the car body section, the section curve of the plastic mold, the profile curve of the propeller blade, the weld curve, etc. For the weld curve, when simulating the weld curve in some studies, the mathematical model of the curve needs to be used, which generally needs to know its mathematical expression in advance. [0003] In mathematics, curves generally have explicit, implicit, and parameter representations. For a plane single-valued curv...
