Problems solved by technology

There are some problems in existing CNC machine tools: 1. The core of NC machining simulation is the real-time and authenticity of simulation. The current simulation algorithm cannot achieve continuous, dynamic and real display of part processing; 2. NC machining The simulation system cannot perform dynamic collision and interference detection on the free-form surface part processing process in real time and quickly, so the real-time performance of NC code detection is not strong

Abstract

The invention relates to a numerical control (NC) machining simulation device based on a triangular binary tree model. The simulation device is composed of a database module, an NC code editor module, and a machining process simulation module. First, tool information, NC code base and machining parameters in a database are integrated to generate NC codes for part machining; then, the machining area under each NC code is determined, and parts are machined according to different distances between viewpoints and surface characteristic conditions of a free surface; and finally, machined work pieces are rendered. The NC machining simulation device has the characteristics of advanced design concept, practical functions and good human-computer interaction. The machining process of parts can be displayed continuously and dynamically based on the conversion of viewpoint distance and the change of surface characteristics, and thus, the purpose of real-time and authentic simulation is achieved. Moreover, collision interference between objects can be detected in the machining process.

Description

technical field [0001] The present invention belongs to the field of numerical control machining simulation. A numerical control machining simulation device is designed, which can continuously and dynamically display the machining process of parts based on the conversion of viewpoint distance and the change of the characteristics of the curved surface itself, so as to achieve the purpose of real-time and authenticity of simulation, and at the same time Collision and interference detection between objects can be performed during processing. Background technique [0002] With the vigorous development of modern manufacturing industry, people pay more and more attention to the machinability of products and the quality of processed parts. The virtual NC machining simulation system came into being. The essence of its processing is that it does not consume actual materials and does not occupy machine tools. Under the condition of using the computer to simulate the actual processing...
