  The objective of the study was to present the architect, training system consideration and performance of Levenberg-Marquardt back propagation algorithm for manufacturing operation selection that can be associated with STEP-NC file generation. Here STEP-based product data modeling, EXPRESS representation combined with neural network algorithm using feature based design attributes such as dimension ratio, tolerance and surface finish etc. It describes the details of training algorithm steps, training data pattern and performance output of the system in association with object oriented data model in process plan data generation. It gives required criterion for extending the system for machine tools and cutting tools selection with reference to turn-mill process planning requirements. Finally summarizes on importance and methods of binding STEP representation and intelligent Computer Aided Process Planning (CAPP) system development.

  Computer Numeric Control (CNC) machine has been widely used in the industries since its development. Today in industry CNC technology has been used for various operations like milling, drilling, packing, welding etc. With the rapid growth in the manufacturing world the demand of flexibility in the CNC machines had been increased. The commercial CNC was fail to provide flexibility because its structure was found to be of closed nature which does not provide access to inner features of the CNC. Apart from that the ISO data interface model of commercial CNC is found to be limited. In order to overcome these issues, Open Architecture Control (OAC) technology and STEP-NC data interface model was introduced. At present, the Personal Computer (PC) has been the best platform for the development of open-CNC system. In this study, a new approach of modern CNC development has been presented that utilized motion control card, universal motion control interface and various functional modules (developed on virtual componenet technology platform) for position, spindle and tool changer motion control. The system was experimentally tested on old 3 axis CNC milling machine and found to be useful to enable sustainable manufacturing environment.
