Automation plays an important role in the manufacturing systems to increase the productivity with high flexibility in the production process. This may leads to the requirement of an information model to control the industrial machinery and processes. The information model contains the common product data. Hence, the data extraction is mandatory to extract the product data from the product model. This paper explains the extraction of product data through feature extraction process. A simplified system is developed to extract the data from the STEP file of a product model for subtractive features of prismatic parts. Using extracted data, the controller dependent NC codes were developed. The extracted data is also useful as reference data for checking the quality of manufactured parts by comparing with the data measured by coordinate measuring machine (CMM). In this paper, the integration concept is explained with the experiments conducted to produce the prismatic parts using the generated codes.
