Abstract


The development of manufacturing CNC machine tools , flexibility and versatility to a higher demand , the gradual increase in CNC equipment developed based on motion control card , but this type of device in the automatic generation of NC code is still rare , mainly used manual programming , heavy workload , limiting its promotion and application in the broader field . Water jet cutting as an important special processing method , and its increasingly widespread application of modern processing . NC program is how quickly and accurately the water cutting water jet machining is an important topic to be addressed . Visual C development tools , combined with a certain type of water jet cutting machine tool motion control card , control system software developed water cutting machine tools based on DXF file . DXF file structure first detailed analysis of a method to automatically extract parts diagram data presented on this basis . Data extracted from the DXF file of graphic elements , and water jet cutting machining process requirements , further processing , water cutting machine tools, machining trajectory is generated . Greedy algorithm - based optimization method that is to change the path in the process of processing the order as well as the control point sequence optimization algorithm for processing disorder, air travel is excessive and trajectory optimization method based on genetic algorithms trajectory optimized, making the processing hollow stroke becomes shorter, to improve the processing efficiency . DXF file is automatically generated NC code format water cutting CNC water cutting program in the format and characteristics as well as the understanding of the water jet machine CNC programming language commonly used code based on the proposed method . This article also designed the NC code compiler , and waterjet radius compensation given radius compensation based waterjet simulation examples .
