Application of AutoCAD in laser processing through the interface of DXF

The movement of lightpen in a laser processing system is analysed in detail.The structure of DXF is analysed and introduced simply, a realizing way is brought forward for the exchanging interface of DXF data,whose advantages and disadvantages are compared with those of poltter(PLT) format in laser processing.The application of AutoCAD in laser processing is realized through the exchanging interface of DXF data,whose results are better than PLT format.
