Abstract

The invention provides a machining calibration method and device for a three-dimensional blank workpiece. The machining calibration method comprises the steps: determining a preset number of first sampling areas on the surface of the three-dimensional blank workpiece; obtaining a first cloud data set corresponding to the first sampling area; obtaining a three-dimensional model, wherein the three-dimensional model comprises a machine tool model provided with a workpiece model; obtaining a first coordinate system of the workpiece model through matching of the first cloud data set and a model data set of a first target area in the workpiece model; obtaining a second coordinate system of the machine tool model; and generating a machining path according to the first coordinate system, the second coordinate system and the workpiece model, and then machining the three-dimensional blank workpiece installed on the machine tool. According to the method, the model data set of the corresponding local area of the theoretical three-dimensional model is registered through the point cloud data set corresponding to the local area of the entity workpiece, so that the data processing amount is reduced and the processing efficiency is improved on the basis of ensuring the registration precision.

Description

technical field [0001] The invention belongs to the technical field of digital processing, in particular to a method and device for processing and calibrating a three-dimensional blank workpiece. Background technique [0002] With the rapid development of computer-aided design technology, it has been widely used in the field of workpiece processing. When the workpiece needs to be processed, the computer processing software cooperates with the workpiece and the three-dimensional theoretical model of the machine tool, and the machine tool is digitally controlled. Processing of solid blank workpieces to obtain finished workpieces. [0003] At present, the three-dimensional surface structure of the workpiece is usually relatively complex. In the process of digital workpiece processing, in order to ensure the machining accuracy, it is necessary to match the three-dimensional theoretical model in the processing software with the physical machine tool and the physical workpiece for...
