Abstract

The invention discloses a numerical control machine tool workpiece machining allowance determination method based on image recognition, and the method comprises the steps: obtaining image data of a to-be-machined workpiece, carrying out the feature recognition of the image data, determining the workpiece shape features in the image data, and determining a reference 3D model corresponding to the workpiece shape features based on the workpiece shape features, the reference 3D model is used for reflecting the workpiece shape of the to-be-machined workpiece after machining is completed; acquiring laser point cloud data of the to-be-processed workpiece, and determining a real-time 3D model of the to-be-processed workpiece based on the laser point cloud data; and according to the real-time 3D model and the reference 3D model, the machining allowance of the workpiece to be machined is determined. According to the invention, the machining allowance can be tracked in real time, and the workpiece to be machined can be machined conveniently.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a method for determining the machining allowance of a numerical control machine tool workpiece based on image recognition. Background technique [0002] With the advancement of CNC machining technology, more and more workpieces can be processed by CNC machine tools. The current CNC machine tools include CNC lathes, CNC milling machines, etc. However, when the current data machine tools process workpieces, they basically call the corresponding fixtures, tools and other components according to the preset processing process information and follow the preset machining process information. The machining path is used to machine the workpiece. However, the machining allowance of the workpiece is not monitored, so that the machining process of the workpiece cannot be controlled. [0003] Therefore, the existing technology still needs to be improved and improved....
