2D AutoCAD Geometric Data Extraction and Post- Processing for Numerical Control
Abstract
In this paper, a method of extracting 2D geometric data from AutoCAD drawing and post- processing for Numerical Control (NC) is presented. Geometric data already available in the Drawing Interchange Files (DXF) can be utilized to accurately and economically prepare part programs for controlling NC/CNC machine tools. AutoCAD, being general
purpose software, stores its geometric data in a form that cannot be directly applied for automatic generation of Numerical Control (NC) codes. The way around the discrepancy between the structure of a drawing database (DXF files) and the information requirement for part programming is addressed in this work. NC programming of a test component
drawn in AutoCAD is also presented.
