Automatic Generation of CNC Part Program for Cylindrical Components from DXF File

Jatin Dave, V R. Iyer

Abstract


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
