Five-axis linkage machine tool numerical control system and processing method thereof

Abstract

The invention discloses a five-axis linkage machine tool numerical control system and a processing method thereof. The five-axis linkage machine tool numerical control system comprises a computer, a CNC (computer numerical control) device, a servo drive device and a machine tool, wherein a CAM (computer-aided manufacturing) software module is arranged in the computer which is connected with the CNC device, and the CNC device is connected with the servo drive device which is connected with the machine tool; the CAM software module sends a signal to the CNC device; the CNC device performs processing and analysis on the signal, generates a position control command, and sends the command to the servo drive device; and according to the position control command, the servo drive device drives the machine tool to run. By means of the five-axis linkage machine tool numerical control system and the processing method thereof, a profile processing route corresponding to a DXF (drawing interchange format) file graph is subjected to reading, preprocessing, unequal step segmentation and cutter compensation processing to obtain final to-be-processed data information; a G-code corresponding to the final to-be-processed data information is acquired, processed and analyzed to generate the position control command; therefore, requirements for high-speed high-precision multi-axis linkage multiple-tool combined machining are solved for light profiles.

Description

technical field [0001] The invention relates to the technical field of mechanical numerical control processing and manufacturing, in particular to a five-axis linkage machine tool numerical control system and a processing method thereof. Background technique [0002] With the development of aerospace, shipbuilding, automobile, energy, metallurgy and other industries, multi-axis linkage CNC machining technology is being widely used in the processing of high-precision complex curved surface thin-walled parts. During the multi-axis linkage CNC machining process, the machining tool path can be reasonably planned according to the part geometry and process parameters, and the corresponding tool position trajectory file can be generated. The file needs to be converted into a NC machining program after post-processing in order to drive the machine tool for processing. [0003] Compared with traditional three-axis CNC machining, five-axis CNC machining can significantly improve proc...

Problems solved by technology

[0004] In addition, in the production of light-weight profiles, the processing of some light-weight profile parts with complex shape curves needs to involve multiple processing procedures such as milling and polishing, and the processing efficiency and processing accuracy are not high. The other is that most of them use single-tool processing technology, and the shaping proc
