Problems solved by technology

However, in the woodworking cutting industry, there are relatively few simulation software, and there are fewer functions to update the 3D model in real time based on path dynamic modification
Moreover, the Boolean difference operation is currently based on topological relationships or grid data to realize the milling process, which requires a large amount of calculation and is difficult to achieve real-time simulation

Abstract

The invention provides a door type processing process simulating method and device, and relates to the technical field of computer-aided design and production processing. The method comprises that door type data is defined, a cutter is configured according to the door type data, cutter track information is generated; a door plate 3D model is created according to the door type data; a cutter 3D model is created according to sectional 2D data of the cutter; the cutter 3D model is controlled to sweep according to the cutter track information, and a cutter sweeping body 3D model is generated; whether there is jet angle information in the cutter track information is determined; if NO, a CSG voxel construction method is used to carry out Boolean operation on the door plate 3D model based on the cutter sweeping body 3D model so as to remove residual material by cutting, and a processing sequence is obtained; and the door plate processing process is simulated according to the processing sequence, and a door type entity model after simulated processing is obtained. Thus, the cutter for the door plate is configured in real time, modeling is rapid, real-time simulation is realized, the time complexity is improved, and the error rate is reduced.

Description

technical field [0001] The invention relates to the technical field of computer-aided design and production processing, in particular to a method and device for simulating the door-shaped processing process. Background technique [0002] Simulation technology based on computer dynamic graphics is relatively mature in the field of industrial processing. This method can dynamically simulate the whole process of workpiece CNC cutting. At the position where the tool contacts the workpiece, the model of the workpiece will perform corresponding cutting operations according to the path of the tool, so that the machining process of the workpiece can be displayed on the computer in real time. However, in the woodworking cutting industry, there are relatively few simulation software, and there are fewer functions to update the 3D model in real time based on path dynamic modification. In addition, the Boolean difference operation based on topological relationship or grid data is curre...
