| Abstract: | The paper analyzes AutoCAD graphs’ DXF files,extracts their coordinate information,and classifies and integrates geometry entities in order to implement a Java interface to parse different versions of DXF files.The paper introduces the minimum rectangular envelope method implementation process as well as the cutting path generation process,at the mean time generating NC codes for layout results.Experiments validate the feasibility and effectiveness of the above method;it improves industrial raw material utilization ratio and company production efficiency;it plays an important inspiring role in DXF applications to layout cutting;moreover it is of practical value to small-and medium-sized hardware enterprises. |
