High-precision repairing method for three-dimensional printed product

Abstract

The invention provides a high-precision repairing method for a three-dimensional printed product. The high-precision repairing method is used for repairing an incomplete workpiece by a three-dimensional printing technology and comprises the steps of obtaining a data model of a qualified product; extracting surface covering points of the data model of the qualified product, calculating the coordinates of the surface covering points, and establishing a reference point coordinate set; scanning the incomplete workpiece, and establishing a workpiece data model according to the scanning data; extracting surface covering points of the workpeice data model, calculating the coordinates of the surface covering points, and establishing an actual point coordinate set; analyzing and comparing the reference point coordinate set and the actual point coordinate set, extracting points in the reference point coordinate set to establish a target point coordinate set, and extracting points only in the actual point coordinate set to establish a default point coordinate set; obtaining a repairing object set according to the default point coordinate set and the target point coordinate set, and designing spraying paths according to the repairing objects; spraying to repair the incomplete workpiece according to the spraying paths. The high-precision repairing method for the three-dimensional printed product can precisely and quickly repair the incomplete workpieces.

Description

technical field [0001] The invention relates to the technical field of workpiece repair, in particular to a high-precision repair method for three-dimensional printing products. Background technique [0002] With the development of automation technology, automatic assembly line production methods of workpieces in industrial production and other fields are becoming more and more common, especially with the emergence of three-dimensional printing (three-dimensional printing) technology, some high-precision products or workpieces have also entered automatic production ranks. [0003] In the process of automated production, due to insufficient material supply or improper control, it is very common to produce incomplete workpieces. At present, for this kind of products, the recycled raw materials are often destroyed directly. In this way, the work of product molding is completely abandoned, and additional destruction costs are added. As far as a single workpiece is concerned, th...

[0003] In the process of automated production, due to insufficient material supply or improper control, it is very common to produce incomplete workpieces.

At present, for this kind of products, the recycled raw materials are often destroyed directly. In this way, the work of product molding is completely abandoned, and additional destruction costs are added. As far as a single workpiece is concerned, the production process is completely dependent on time, technology and raw materials. waste

Moreover, the higher the precision of the product, the higher the possibility of defective products and the more serious the waste
