Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a method for virtual assembly and numerical control machining simulation of a double-turntable five-axis numerical control machine tool. Background technique [0002] In manufacturing, free-form surfaces are usually processed by five-axis CNC machine tools. A five-axis machine tool adds two additional rotary axes to the commonly used three-axis machine tool. The simplest configuration of a five-axis machine tool is as follows: on a general-purpose vertical three-axis machine tool, a double turntable is installed to form a double turntable five-axis CNC machine tool. The two axes of rotation provide greater flexibility, enabling the machining of high-quality complex free-form surfaces that were not possible before. In terms of cutting effect, five-axis machining has many advantages, one is high cutting efficiency, the other is high surface precision of workpi...

Problems solved by technology

[0004] The processing simulation of five-axis CNC machine tools has been integrated in some CAM software, such as UG, Cimatron and other software. These integrated software are suitable for generating NC codes. Although some processing simulations can be performed, the connection part of the NC code cannot be simulated. , In addition, it is impossible to customize the unique macro program simulation, and it is impossible to set parameters such as the actual machine tool stroke and volume cutting amount per unit time, so that the correctness of the numerical control simulation cannot be fully guaranteed

If VC++ and OpenGL technology is used to develop NC simulation software, the workload is very large and the difficulty is relatively high. For local modification of the machine tool structure, changes in the machine tool CNC system, etc., it is necessary to re-modify the software code, so that the simulation efficiency is relatively low.
