his paper describes the methodology for the automatic extraction of the co ordinates from dxf file and generation of CNC part program for the cylindrical components. The paper uses the method discussed in the survey for the extraction of the co ordinate from dxf file and recognition of some basic feature like horizontal line, vertical line and inclined line. After collecting the co ordinates the algorithm is developed to arrange these coordinate to write a CNC part program. While arranging the co ordinate, sequences of the features are also considered so that it will be useful in creating tool motion. For writing a CNC part program, the practical aspect like depth of cut is also considered and sequence of features are also taken care so that proper tool path is generated. his paper describes the methodology for the automatic extraction of the co ordinates from dxf file and generation of CNC part program for the cylindrical components.
