Abstract

The invention relates to a planning method for processing the length of a safe and shortest knife by adopting five-axle numerical control, analyzing component manufacturability and programming a smooth cutter path. Firstly, a maximum value of the cutter length is set within the range allowed in the technology; disc of the cylindrical surface for the knife rotation at the positions of knifepoint and a barrier are gridded, and through the depth testing of video card and the function of blocking and querying, the reachable information and safe shortest length of the knife in a reference direction can be obtained, and the reachable direction cone of the knife is programmed; then according to the restriction to direction continuity and processing environment, the feasible direction cone is calculated and the manufacturability is judged. If the programmed knife is manufacturable, the length of safe and shortest knife of a knifepoint sequence is programmed in the feasible direction cone in a dynamic planning method, and then a smooth knife path is programmed. The method of the invention has high efficiency, simply realized programming, can be applied to 3 plus 2 axle numerical control processing of complex components or knife choosing and path planning of five-axle linkage numerical control processing.

Description

technical field

[0001] The invention relates to a planning method for the safe shortest tool length of five-axis numerical control machining, which is suitable for five-axis numerical control machining of complex parts and belongs to the technical field of computer aided manufacturing (Computer Aided Manufacturing, CAM). Background technique

[0002] CNC machine tools have been widely used in the manufacturing industry. Compared with traditional three-axis CNC machining, five-axis CNC machining can significantly improve processing efficiency, enhance tool accessibility and shorten tool length, providing an effective solution for the processing of complex parts. means. Due to the change of tool posture, the length of the tool can be shortened under the premise of avoiding interference, but the change of tool posture also greatly increases the difficulty of tool parameter selection and tool path planning. The current tool length planning mainly relies on the trial and error me...
