Abstract

The invention discloses a virtual machine and actual electrical machining simulation method for a five-axle number control machine tool, which is used for simulating the machining process of the five-axle number control machine tool. The method comprises the following steps: modeling the five-axle number control machine tool, i.e. performing simulation modeling and graphic displaying to the machining process of the five-axle number control machine tool; virtual machine tool motion and machining simulation, i.e. respectively simulating the motion and the machining of the five-axle number control machine tool; and data acquisition and transmission, i.e. detecting the variation of data quantity in a virtual environment through a data sensor and then a virtual mechanism is driven to move. The invention realizes the visualization inside a three-dimensional entity; a local refreshing technology is adopted on the graphic display aspect during the simulation of the machining process, so the simulation effect and the graphic display efficiency are ensured; and the multi-threading operational mode increases the response speed of the application program. The invention can greatly enhance the machining simulation precision of the five-axle number control machine tool.

Description

technical field [0001] The invention relates to a method for processing simulation, in particular to a method for virtual machine real electric processing simulation of a five-axis numerical control machine tool. technical background [0002] In the manufacturing industry, free-form surfaces are usually processed by five-axis CNC machine tools. A five-axis machine tool is based on the commonly used three-axis machine tool with two additional rotary axes added. These two axes 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 workpiece after machining, and the third is that it can reduce the amount of manual grinding. However, due to the addition of two rotating axes, interference is prone to occur during five-axis CNC machining. Interference can occur between m...
