In this study, a feature based parametric design program including manufacturing features which are used in machining of prismatic parts by chip removal methods has been developed. Prismatic parts modelled in the feature based system can be modified parametrically by the developed parametric design module. To modify the part model parametrically enables feature based modelling process to be flexible and easy In the developed program. the features which are added to the models prepared by a feature based design program are evaluated by the expert system module and They are used in part modelling after determining of their compatibilty according to the rules. The aim of this study is to model the manufacturing features such as a pocket, slot and hole that are used in machining operations by adding to prismatic parts, to enable the modification of the part model parametrically and to warn, inform and guide the user for design and manufacturing mistakes. The system has been developed in AutoCAD using AutoLISP language.
