Abstract

The invention discloses a UG-based propeller overall numerical control machining method. The method comprises the following steps: for various kinds of propellers, carrying out modeling in UG NX; carrying out editing through a UG CAM processing module to generate a machining tool path trajectory; translating the tool path trajectory generated by the UG CAM processing module into NC codes, which can be identified and used directly by a CNC machine tool, through a VC++ programming postprocessor; carrying out machine tool modeling through VERICUT software, and then, inputting the generated NC codes into the software for machining simulation verification to check whether the phenomenon of undercutting, overcutting and interference and the like exist; and finally, carrying out cutting speed optimization through an OptiPath module of the VERICUT software, so that the machining speed is optimized by adding speed codes to the original codes on the premise of not changing the NC machining codes.

Description

technical field [0001] The invention belongs to the technical field of multi-axis processing, and uses a heavy-duty seven-axis five-linkage gantry milling machine tool to process and manufacture marine propellers, and in particular relates to a set of numerical control processing methods for the whole propeller. Background technique [0002] Propellers for large ships are the core components of heavy power machinery such as ships, and their processing quality directly affects the performance of the propeller and the service level of the ship. The working environment of the propeller is harsh and it takes a long time to work, and the propeller with low processing quality will cause problems such as excessive noise and premature wear. For a long time, traditional processing methods have been used for propellers used in large ships in China: sand mold blank casting, grinding wheel grinding (semi-mechanized initial grinding, manual fine grinding), and sample inspection. The tra...
