The rapid advancement of information technology and its integration with the
manufacturing technology increased the necessity of consistent and coherent
data flow in the chain of Computer Aided Design (CAD)-Computer aided
Manufacturing (CAM)-Computer Numerical Control (CNC). To achieve this,
ISO 10303 standard (STEP), developed by ISO, is seen as a solution since
STEP is independent of the environment on which design data, manufacturing
data or machining data produced. In this thesis, efficiency of NC-code
generation, with the inclusion of process planning data, from a STEP based
CAD data is investigated. For the investigation purposes, software responsible
for both building the STEP based CAD data and generating related NC-code
automatically is developed. Using this software, several parts are designed / generated NC-codes are verified via CNC simulators and some test parts are
produced. STEP AP224 based feature modeler, developed specifically for 2-
axis rotational part design, includes / feature library, feature modeler
employing SW2007 via API for visualization and preprocessor responsible for
generation of STEP file in neutral format, called STEP Part 21. The NC-code
generator includes / postprocessor responsible for STEP Part 21 interpretation,
CNC machine tool and cutting tool database and preprocessor responsible for
NC-code generation.
