Abstract

The invention discloses a novel method for simulating a machining process of a five-axis numerical control machine tool. The novel method comprises the following steps of: modeling the five-axis numerical control machine tool, namely performing simulation modeling and graphical display on the machining process of the five-axis numerical control machine tool; simulating the motion and the machining of a virtual machine tool, namely simulating the motion and the machining of the five-axis numerical control machine tool respectively; and acquiring and transmitting data, namely detecting the change of the data quantity in a virtual environment through a data sensor and driving the motion of a virtual mechanism. According to the method disclosed by the invention, the interior of a three-dimensional entity is visible; during simulation of the machining process, the graphical display aspect is performed by adopting a partial updating technology, so that the simulation effect and the graphical display efficiency are guaranteed; by adopting a multi-thread working mode, the response of an application program is improved; and According to the novel method, the precision of the simulation for the machining process of the five-axis numerical control machine tool can be improved greatly.

Description

technical field [0001] The invention relates to a method for processing simulation, in particular to a new method for processing simulation of a five-axis numerical control machine tool. Background technique [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 moving tools (tools and fi...
